Beijing bikini
"Beijing Bikini" is a well-established satirical name for the practice of men in China, in hot weather in public places, rolling up their T-shirts or tank tops to the chest, exposing their stomachs, in order to cool the body. This practice is most often characteristic of middle-aged and older men.
It is also called "success belly"
Simply a way to show that you are rich and have a lot of food. (Except that you can look like this when you are completely broke and surrounded by cheap, processed, high-calorie food)
