As a fat man with a weight of 100 Jin, I used to put up a flag on the first day of every month, and I must lose a few Jin this month.
Stick to it for one or two days every month, and then go to eat delicious food on the third day. From then on, I forgot to lose weight and failed to lose weight every time. Now I am a big fat man with a weight of 100 kg. I'm really happy.
