After graduating from University of Arizona, I went back to China for six weeks to apply for a new U.S. visa.
Since weightlifting has become a part of me, I continued my workouts in a Chinese gym.
The experience there is significantly different from American gyms.
Annual Membership, Please
Most gyms in China only sell annual memberships.
Gym managers are secretly wishing that you would give up your ambitious exercise plan after several weeks, so that they could profit off you without devoting resources.
My stay in China was six weeks, so an annual membership would be overkill and prohibitively expensive.
I had to find a gym that offers single tickets.
My gym of choice was "Fitness Club" (菲特妮斯健身会所) located in the basement of a grocery store.
They agreed to offer me single tickets at ¥50 per visit.
In United States, most gyms are happy to sell you a day pass.
Some gyms even offers a few free tickets so that a potential customer can experience the facility; this is also perfect for short-term visitors.
In terms of price, ¥50 per visit is about as much as $8 charged by University of Arizona Campus Recreation Center.
However, personal income in China is much lower than the United States, which means a Chinese gym costs more than an American gym for local people.
After six years in Arizona, I graduated from The University of Arizona, and returned to China on Sep 01, 2017.
My previous returning to China was in 2014, and China has changed greatly during my three years of absence.
Swipe Your Face
Fraud is a serious problem in China.
The "standard" countermeasure is two-factor authentication, i.e. a random code sent to your phone.
However, fraudsters have been able to convince the victim to reveal the random code on their phone.
A stronger countermeasure is doing all transaction in person: you have to show up at the bank or phone company, and present your ID card.
However, there are usually long lines in those places and thus it's not a pleasant experience.
The regulators invented a new way: "swipe your face".
I bought a SIM card for my smartphone online.
To activate my account, I must upload a picture of my ID card, and record a video of me acting according to a series of random instructions.
The instructions could be: "blink your eyes, open your mouth, rotate your head to the left".
The system would then analyze the video to confirm that I am alive and am the same person as shown on the ID card.
I believe video authentication provides much stronger authentication than asking for "mother's maiden name" and "last four digits of social security number" as most companies do in the United States.
It is surely less convenient than answering a few questions, but this is a trade-off for China where fraud is more common.
