Exercises, music, work and sleep

Reading Time: 2 minutes

I talked about my recent exercise trend here. But I think I need to focus on my sleep a bit more, as in recent years, due to various reasons, I didn’t get the necessary sleep and that is taking a toll on my health.

As I reflect back, in addition to aging, work at MC is one culprit of my deteriorating sleeping quality. I talked about my on call experience of that employer (in Chinese) here.

Fortunately both my last job and my current job are less demanding, and less stressful. But I am getting older too 🙁

Recently I started to listen to music during sleep. That alone may not be the best solution for “not being able to fall into asleep”. But I am fine tune it, as well as adjusting so that I don’t listen to my iPod Nano (I talked about it here and here), or a new MP3 player I bought the whole time.

Also, back to exercise, I think in addition to swim or walking, I am going to focus a bit more on meditation, such as breath on Apple Watch or Yoga via YT (see my YT Yoga playlist).

PS:

I got to see my uncle (my mom’s little big brother, who is 89 years old) this summer. He commented on the sleep problem we have. He said, not exact words, but why we are worrying about things in the night? His point was we probably had too much stress from our day job (which is probably true). Back to the time when he was young, he probably doesn’t have the material things we have now, but he is much happier. Probably one reason he lives to 89 🙂

(Update 10-17-2025) I just came across this at FB “What is Success? Success is being able to go to bed each night with your Mind at Peace.”

PS 2:

To my fellow HS students’ parents especially parents of student athletes: now we have this AI thing – let AI do the work and let our kids and all of us have some more sleep 😴 (not my words, coach and my uncle’s words – they are wiser than me. Okay I added this AI thing for dramatic effect [捂脸]). Btw, tonight is the blue and white night at #LHWHS and if you have time (no impacting on your or your kids sleep schedule): the girls powder puff flag football game is fun to watch. #homecoming #powderPuff

PS 3:

年近退休睡觉不爽, 有招了

I did one thing similar: something I mostly figured out my own, with some inputs from friend(s). I listened to Cantonese music (slow music, more like lullabies). Do you want to guess which musicians (singers) I listened to most often? Btw, I mostly use my 13-year-old iPod Nano (as shown here). Because it doesn’t have the fancy stuff on my iPhone and won’t pull me into the blackhole of “doom scrolling”.

I think in theory at least, a podcast or a book would do the similar trick. I mostly just listened to one song non-stop (loop) – a side benefit is it saves the battery of iPod Nano.

Uber driving tips

Reading Time: 8 minutes

(03-01-2025) I just realized today is Madi Gras. This morning I drove 3 trips. First trip: from Rock Hill (near old Warson road) to Kirkwood. 2nd trip: from Kirkwood to South County. Last trip: I drove back to CC, drove a gentleman across the Olive road, from the Courtyard Hotel to the office building across the street. The last trip was worth the money as I needed to come home.

I also had a minor issue when the train was blocking the Geyer road. I had to use Apple Map to make a detour, before switching back to Uber Driver app. This is the 1st time I used Apple Map instead of Uber Driver map for navigation because of road/traffic condition.

At about 1 pm, I also realized it was Madi Gras celebration and no wonder the Uber Driver app shows quite busy and surge prices in many areas. And I also recall my passenger brought beer to friends’ house and he sounds like opened the beer can in my minivan – I didn’t look whether open drinking in the car is legal or not (many years ago I heard from friends who have lived in NY saying it’s illegal in NYC).

(02-16-2025) I drove 2 trips today. One in the early morning, and another one between 10 and 11 am when I was taking my 10 year old to her drawing class (I didn’t have much to do, plus it was too cold to walk outside today). I didn’t know or anticipate we would have snow overnight. The first trip has two legs, the 1st one is from near the Costco Business Center (St. John) to Maplewood (the lady dropped her kids there), then from Maplewood I drove the passenger to a senior living home in the Tower Grove neighborhood where the lady worked for 12 years so far. It’s on Magnolia road, north of Tower Grove park. So overall my minivan has been helpful because I carried 4 people for the 1st leg of the trip (the longer one too).

(02-14-2025) It seems Uber is getting cheaper comparing my Uber trip to airport back in 11/27/2019 vs today I drove a passenger to the Airport (comparable location). I cannot ask passenger how much she paid, but I am using 40% for Uber’s cut. $9.42/0.6 + $3 (tip) = $18.70. In 11/27/2019 I paid $21.48 for trip from my home to STL. I realized one factor: the trip starts at 4:46 am (vs 7:12 am). Bogleheads has a thread too.

Perhaps more importantly, I picked up a trip when I was near the airport, and now I realized it was not worth my effort moneywise, it’s from 63121 near highway 70, to St. Mary High School in South City: 16.5 miles and 28 minutes one way, my fare (earning) is $14.41. Note the plus side – I got to see or drive some of the places I haven’t driven until today, from the north county, north city, downtown (gateway arch) to the South City. I saw the Love gas station, the factory or warehouses, 1st time driving into downtown from highway 70, and transition to 55. Many things look pretty impressive: including the Budweiser plant and the St. Mary HS.

I should probably stick to my one trip a day pledge 🙂 || The reason I turned on the “accept new request” thing is I thought I may be able to pick up a trip starting from airport, after the drop off, it happened to me once – but I guess that kind of luck is rare.

(02-10-2025) I continued Uber driving this morning. I got a repeating customer. Note on Uber a rider cannot designate a driver, but he/she can choose service (Uber X, Uber XL etc.) and so on. The matching part is determined by the system (platform). I think from now on, on weekdays, I am going to just do one trip in the morning (with the exception of airport ride). I am also going to just accept the pickup within 10 minutes of driving.

(Update 02-09-2025) I resumed my Uber driving today. From now on, I will probably only drive on Saturday and Sunday, couple hours at most each day.

(Update 02-08-2025) More about Go Go Grandparents ride (here is a reddit thread if you are interested). Now I recollect, the Go Go Grandparents people kind of tricked me in some way, because initially it was a ride for $4 or $5 and it’s a one way trip (probably from the old gentleman’s home to the McDonald’s at Maplewood, off Hanley road, near Home Depot store). Then once I was on the way (after took the rider), Go Go Grandparents updated the trip, so that I can also bring the gentleman home: made it a round trip. The total is about $7. But because the rider asked for extra stop at the gas station, and I need to help him get off the car, back out my car, etc., it made my 2nd already booked trip a bit late – it’s possible the rider for 2nd trip gave me a score of 4 because of that.

A side note of this is: the starting address is across the street from the real house the gentleman was living in (because I drop back to his home, and I have the address, which I dropped off his phone later, btw). I don’t know why the discrepancy. The house was a bit run-down, which seems to match the old gentleman’s life stage. I saw broken down car in the backyard. Next time, if I ever encounter similar issue (lost item in my car), I would take a picture so that it would help me resolving the issue.

Before the trip on 01-28-2025, I did two trips that were either Uber Health or called by people like Go Go Grandparent. I mentioned one on 01-23-2025 (see below). In another case, I just drove a gentleman (a veteran) from his home to BJC in central west end. I don’t mind drive people for medical appointments etc., but from now on 02-09-2025 I will probably just drive on weekends (leisure time), as well as not taking Go Go Grandparent (not sure how best to distinguish/decline).

(Update 02-03-2025) Rideshare Safety Tips: A Complete Guide

(Update 01-28-2025) Once again please be aware of Uber Health – or those rides arranged by the Caregivers. I got such one again this morning: the ride is taking a gentleman to McDonald’s, order food, and take him back. On the way back he asked me to stop by the gas station: he said he left his debit card there last time. I did him the favor in terms of the extra stop. I also helped him the food and drink during drop off to his home. But he forgot his phone (left it on the seat) in the end. I had to make an extra stop and drop off his phone after I drop off my 2nd passenger. Last but not least, it seems between them I got a 4 star. Later I got a call from gogograndparent (FB page for GGGP) that they are the Uber coordinator. It went to my voice mail as I usually don’t pick up phone from stranger. Looks like they are Chicago based.

This is probably going to be my last Uber driving for a while. I am not overly concerned about the phone itself, but it seems there are quite a few caregiver responsibilities that comes with this kind of Uber driving. Also the customer service stuff (which I got a glimplse when I worked for Mastercard). I think ideally I want to be like the Costco and pick the ideal customers.

Now I am thinking about becoming real estate agent next (part time though).

(Update 01-23-2025) I did a few more trips this week, including during the deep freeze (Sunday to Wednesday morning). I feel some people are appreciative: e.g., on Sunday I dropped off a caregiver from apartment near my home to Delmar Garden, a senior living place near 141 and 64. The lady told me one driver bailed on her: she gave me $5 tip. Yesterday I drove a lady from her home to dental appointment: she gave me $5 tip too. Another trip was for a WUSTL undergrad (senior) from his home to medical school. The day before it was similar: drove a nurse from Mercy Creve Coeur campus to her apartment; then drove a medical school student to WUSTL medical campus.

This morning, I declined a few far out of way trips (I think it’s a bit too much if I need to drive 15 to 20 minutes to pick up someone, via highway). I picked up a lady at Westport and drop her off STL Lambert International airport. On the way we stopped by the Panera Bread at Westport (at her request). She gave me $7 tip.

Today also marks the day that I drove 100 trips (I started on 10-13-2024, as shown in my blog post here). Technically I think it’s 101. As I drove for an old lady after I cancelled the trip because she didn’t respond in time. Uber did give me the money via adjustment later on. Below was the story on Jan 13, 2025 (note the temperature was low, but more importantly road condition was still not perfect after the snow storm).

A bit unusual Uber driving experience this morning. I picked up the ride during my 1st trip. Just as I was going to pick up the passenger for this particular ride (2nd trip), the Uber platform told me the passenger doesn’t do text, via a medical (care) coordinator. I arrived the apartment, did call, text to the number given by the platform. No response. But just as I cancelled the trip, and ready to leave, I saw the passenger – an old woman with cane. She is going to the Mercy Hospital in Creve Coeur. The parking lot for the apartment is both icy and slippery, and I slipped, and almost fell. She said she was just locking her door. I said: okay I will take you. I drove her to the Mercy Hospital which I briefly worked for 18 months between 2013 and 2015. She said she didn’t eat breakfast – somehow, she reminded me of my grandma and my parents nowadays (as they are aging).

(Original 01-18-2025) Last Sunday, as I dropped off one passenger on United Airline gate, the next ride came. My lesson learned: keep the Uber Driving app online. In the past, sometimes I turned off new request when I drove into airport dropping off passengers.

This evening, I dropped off a friend at Southwest Terminal 2. But the Uber Driving app told me to go to the STL waiting lot. I was hoping to get a ride right there, and I was not going to waiting lot.

Some safety features for the drivers

Don’t drive during the night, or early mornings, basically when it’s dark outside. Quite recently, once I woke up early, it was New Year’s Day (01-01-2025), as I drove around for Uber, I picked up a ride for 2 guys. I was not 100% sure what those 2 guys were doing, I suspect they were drinking and f?!x around, as I heard a bit of their conversation re: women etc. I have zero intention to learn their business. There was a small incident during pickup too, I parked, one guy came aboard: he took the seat behind me. Just as I was pulling off, I saw another guy pull my door or knock on the windshield, asking me to stop. Turns out he is another passenger. The ride was not eventually, until the end, turns out two guys have a slightly different destinations: one guy lives about one mile from another. They did give me $10, and after my Uber ride is over, I used Apple map for navigation dropped off the other guy. Note Uber does allow for multiple stops and they are probably not sophisticated Uber users and didn’t use this multi stop feature.

Set the minimum rider star rating (score) to 4.5, unfortunately we need to do it every time we go online. I used to set minimum to 4.5, but the article says Any lower than 4.6 could be a potential issue, because it’s at this point that Uber can consider deactivating your account.

I saw from this Reddit thread one driver says 4.85 for Uber. But I also saw some passenger’s rebuttal. Just copy one back and forth below:

======

Driver: Anything under a 4.8 is a no-go. 10 years driving rideshare.

Rider: I am 4.79, always respectful and tip well. Just had a few too many drivers give me a 4 instead of a 5. The rating system is BS and you are losing money by rejecting perfectly good passengers. Now if someone had a 4.2 or 4.1, I’d understand why you wouldnt pick them up.

======

Go offline if we are not familiar with the destination or area: I did this once at East St. Louis. I didn’t realize the ride was going to East St. Louis at the beginning. It appears a security guard was getting off work at Clayton and went back his home in East STL.

I will add more as I think of some more tips.

Last but not least: some other blog posts I wrote re: Uber driving

China Trip Spring 2023 – logistics

Reading Time: 6 minutes

(Update 04-08-2025) After 2 years, the sim card I mentioned below no longer works. After the painful steps of taking pictures and so on, it gave an error message saying that “the number is already being used”. So, I no longer recommend it. We bought another sim card after return the not working one. Will post an update once we get the new one working.

(Update 04-28-2023) Please note the airlines no longer ask/need #COVID #testing from April 29: 4月29日起飞往中国不再需要核酸检测,自测抗原即可。登机前航空公司不再查验检测证明,只需海关健康申报二维码。source: #flychina https://flychina.com/update.asp || This is good news 🙂

(Original) I have a twitter thread here, and quite a few YouTube shorts or videos on this trip (hashtag: #ChinaTrip2023).

But I think it’s probably worth an article or two for me to put down the life cycle of the trip, from planning, buying the tickets, to execution (the trip itself, flights, transfers, and entering/leaving borders etc.), as those tips may be helpful for overseas Chinese or some other international friends to visit China. I think it maybe helpful for me to refresh my memory too, for example, today at #STL I forgot where should I wait for #Lyft or Uber: the Lyft app itself says where, btw. I had to admit that I haven’t flew for a while: I believe my last trip via STL is the PVG trip before pandemic (Nov/Dec 2019). Another example, related matter, I forgot the allowance of luggage is one, and I have to pay either 10,000 miles (Delta Skymiles) or $100 (United Airlines) for the 2nd luggage.

Air Tickets

I bought mine at Expedia.com on Jan 29, 2023. Other good place to buy/check ticket is flychina.com. I flew from my city to DTW, waited for 12+ hours, and from there flew to PVG (direct, no more stop at Korea/Seoul Incheon (ICN) ). On the way back, I took UA 858 that’s PVG to SFO, and later transferred at ORD(a redeye flight from SFO to ORD), before coming home. There was some hiccup in terms of changes and posting the miles to the frequent flyer miles. I believe after I booked the United Airlines Mar 29 flight from PVG to SFO, United likely added number of flight per week, thus making the Mar 29 departure flight no longer available. That’s why I moved to Mar 30 departure date, and have the SFO to ORD redeye flight. The change process in the United Airlines website was relatively smooth. Another small issue was it was long time ago that I bought air ticket on Expedia.com, and unfortunately I still had the old United frequent flyer number on Expedia, as you may know United adopted the Continental frequent flyer number post merger (which I have in my United account). Long story short, as of now, we can claim the miles via this web page. The miles were posted for me immediately after I submit the form 🙂 Update 04-10-2023 NYTimes has an article explains the air ticket shortage situation – China Has Reopened to Tourists. The Hard Part Is Getting There.

Get a China SIM card

(04-04-2023) I am reporting back: this card is decent. It worked on my iPhone 5 (initially I put the new sim card in this old phone), after I turned it off and back on when the airplane just landed. I quickly swap it into my iPhone 12 on the subway (Metro line 2 from PVG to SHA, and I stayed at hotel near SHA, Hongqiao Hub). A student with Tufts U was able to make call to her dad as her sim card was expired. This card is called 蜗牛移动 4G in China (a resller of China Unicom 中国联通). I am guessing it’s small reseller: the idea here is similar to MintMobile vs T-Mobile in the US (mintMobile is a reseller of T-mobile). There was one glitch when I was trying to get 随申码(英语:Shanghai QR Code) at SJTU Minghang campus. The guard said probably my internet on the phone was too slow. It took me quote a few tries to get it work. There are one glitch: no caller ID (and I don’t know how to fix it). Another tip is don’t worry about the “warning message” in Chinese regarding data usage. It will ask one to 充值,I did not read the descriptions on Amazon. But I just trust the title or subject that says 30 days 3G data. So I just ignore the periodically message asking me to refill. As I don’t see the internet stop working after the “data used up” message.

Mandatory paperwork to enter China

Mainly we need the PCR test and also the health code (2D or QR code, commonly called 海关指尖码 in Chinese) via WeChat mini-program called “Customs Pocket Declaration“ or in Chinese: 海关旅客指尖服务. In order to fill out the form, one will need the flight number and seat number. This code has a an expiration time, but can be updated. Again make sure you have a smart phone and ideally the phone can get to Internet via cellular data, because WiFi sometimes is not very reliable at airports, and you don’t have to make this your weakest link for your carefully planned trip to see “long time no see” family and friends.  

Check in at my local airport and get boarding pass at DTW

My local airport agent asked for all the paperwork, but she still has trouble check in my luggages all the way to PVG. Her senior colleague (who looks like a Japanese descent) was able to fix. I also tried to get boarding pass for DL389 at the Delta Helpdesk: it was a fun experience for the two agents there as they don’t usually do that job. It’s usually the DTW DL389 (DTW to PVG) gate agent’s job. The latter gate agent talks a lot about the PCR tests and the health code before departure. They actually check all the relevant documents including the PCR test, before put a “checked” sticker on the passport. The boarding identity verification is done by facial recognition, btw, which surprised a senior Chinese citizen a bit. More on facial recognization latter.

Entering China

Show the QR code the 海关指尖码, then proceed to border agent. After that it seems pretty smooth, and I only saw the customs people check a (I assume) service dog.

Leaving China

Boarding pass plane open at 4:30 pm for UA 858 for 9:05 pm departing time. An older gentleman asked my help (borrow my Visa credit card) to pay the $100 extra bag fee (they don’t take cash or Chinese credit card). Note one still need to do a new health code (2D or QR code, aka 海关指尖码) and scan the code when entering the international boarding gate. The United gate agents checked in some carryons free of charge as they worry the overhead bin space is not enough for all the carryons. Similar thing happened to me (my carryon) for my SFO to ORD flight (in my case, once checked in, it goes to final destination without my intervention). So make sure you take out essentials (paperwork, phone, battery park, water bottle etc.) as you will need them for the remaining of the flights/journey.

Re-entering the US

One only need to show green card (for permanent resident), and their camera look at the face, as well as some finger printing scan. The agent who serviced me was not nice though. Note for those hold B and F visa, they will need to show the vaccination records when getting the boarding pass. This is not required for US citizens and GC holders.

Tips for travel in China

Mobile phone with data plan, here is one possibility to get a local number (Amazon Associate Link).

Apps nice to have: WeChat (and WeChat Pay 微信支付) or Alipay 支付宝。#高德地图 (GaoDe Map) for navigation and get #网约车which is similar to Uber/Lyft in the states. I know WeChat and Alipay can get the 网约车too, similar for #滴滴出行。All those apps will need a mobile phone (likely with a Chinese cell phone number) as well as identity verification (not sure how it works for a US passport holder).

Useful links and resources

回国机票价格表和检测规定: https://www.flychina.com/update.asp (in Chinese).

Also look at 美国-中国 直飞航班专区 section: right now there are direct flights between 6 US cities and mainland China (note the flights are not daily, the most frequent one seems to be the SFO to PVG flights, 5 times a week). The 6 US cities are: LAX (Los Angles), JFK (New York), SEA (Seattle-Tacoma), DTW (Detroit), DFW (Dallas Forworth), and SFO (San Francisco).

If you live in or near those 6 cities, consider yourself lucky. Because the connection time for people from other cities can be long, and number of connections are usually more than compared to 2019: e.g., I usually transfer at ORD Chicago O’here before pandemic because both AA and UA offered daily flights to PVG. In fact, now I recall I took the United Airlines flight last minute in Mar 2007 to see my then girlfriend (now my wife, I have an old blog post dedicated to this). Did you notice anything interesting regarding the blog post’s published date 🙂

What’s next and upcoming

I think I will write up some of my observations and thoughts for my trip as well, e.g., the emergence of EV which is much more than just Tesla here. Or to be more precise, I understand it’s Tesla plus a few more here, such as Polestar, Ford Mach E, Lucid, Rivian and Ford F-150 lightning, but in China, it’s BYD (Build Your Dream) in the leading position, with Tesla following, and followed by Nio/Xiao Peng/Li Xiang (all 3 companies stocks listed in the US, they are $NIO, $XPEV and $LI), as well as many players such as 零跑汽车(Leap Motor, it’s traded in HKSE as HKEX: 09863): their C11 is very impressive, btw, I would trade my Sienna with it in a second. Too bad I live in a country there is really two choices: model 3 and model Y (I hate model X’s funky doors). What I really want is something like Leap Motor’s C11 (small SUV with 600 km which is about 400 miles range 🙂 || Incidentally I came across this article abut China EV industry – China auto show highlights intense electric car competition.

CFA

CFA testing day experience, thoughts

Reading Time: 3 minutes(Update June 8 ) Read couple interesting blogs on yesteday CFA exam. This one from Singapore, and another one from China (in Chinese).

(Original June 7) After came back from the Hilton hotel testing center, I went directly to Schnucks store, to get the Stella Artois beer, and 3 oranges. Why 3 oranges, because I saw 4 for $3. Apparently my mind is still stuck in the CFA exam: caculation on net income, cash flow blah blah blah. When I first saw the receipt shows $2.25 for 3 oranges, I laughed to myself: under normal circumstance I would just buy two for $1.50, much easier calculation. Anyway, if you came here looking for test specific things, I am afraid you will be disappointed 🙂

But I still like to write down some of my thoughts for the test and in general.

CFA test grading
(Grading paper for CFA test, source: CFAInstitute).

1) More people attended the test than I thought
In the grand ballroom at Airport Hilton, I counted there are roughly 300 (14*2*12) people for level I and II candidates. Why so many people and what is the composition of test takers? I saw both new graduate, MBA students and professionals. I am the rare amateur. Let me quote the press release from CFAInstitute which shows growth of CFA candidates in year 2008 vs. year 2007:
