Two of the things I feared before going into exile in Mallorca were Late Dining and Siesta. Covid came and made the former impossible because all the restaurants were closed, and then came the somewhat weird-even-for-me rule that restaurants should close at 5pm. Dinner at 4pm! Yaooooo!
The siesta thing, yes, it's definitely a thing, but mostly for government related offices and shops with just one person. It doesn't inconvenience me too much. However, I have never heard anyone use the word siesta and it's certainly not written anywhere. It's just around. Where implemented the siesta is long, up to three hours, but I suppose it takes time for people to get home if they don't want to sleep in public.
The Chinese, being - how can I put this diplomatically - slightly less prone to leisure, also need rest of course. But why would they close down a busy shop at lunchtime? That's when people need them to be open! Also, why would they waste money on transport just to go home and then back to work when they are already at work?
For this and many other reasons, Chinese sleep wherever they are.
I have seen guys sleeping under trucks, in trees, and once in Mong Kok (Actual name: Wong Gok) I saw a guy sleeping on top of a metal pavement railing. Women sleep in public too, but perhaps more demurely and with their heads resting on the counter or on a sack of dried mushrooms.
Me, I'm a bit reluctant to sleep in public - what if I drool or snore? But I will certainly sleep at home at night! And to avoid lethargy and drowsiness the next day, I go to bed early. I mean, so early it is frowned upon in some quarters. So I don't do dinner at 10, 11 or midnight, even with curfews lifted. When in Rome, yes, but I won't go against my biology. Also it's fattening.
Verily, there are many interesting things about the Chinese culture.
