The whole poem is as follows:

Pangshi

Every holiday, you will gain three kilograms. Take a closer look at three kilograms.

Try hard to lose weight for half a year, and you will succeed in the New Year.

Thin people are versatile, and fat people are useless.

Being a stranger alone in a foreign land will gain three pounds every holiday.

If you know where your brother is crawling, you will eat less pork every time.

Simple obesity patients have relatively uniform body fat distribution, no endocrine disorder and metabolic disorder, and their families often have a history of obesity.

For obesity, there are many factors, including genetic factors, social environment factors and some psychological factors. If you don't pay attention to exercise at ordinary times, it may also lead to obesity.
