How to get the jet lag from China to the United States and how to get it back?

When starting from the United States, I do nothing but eat and go to the toilet as soon as I get on the plane, especially after dark, thus halving the time difference on the plane. It should be daytime in China, so don't sleep. Go out for a walk, do simple exercise, drink some tea or coffee, chat with others, and try not to sleep until dark. When it is night in China, you may not be able to sleep and drink some hot milk. The next morning, according to the time in China, I got up at 8 o'clock, went out for a walk and did simple exercises like the first day. In a day or two, the time difference will be reversed.

Then you can be as chic as you want, just like in America.

When you return to the United States, the operation method is the same. The jet lag will come back soon.
