"The king of Chu has a thin waist and starved to death in the palace" means the king of Chu Ling.
the king of Chu has a thin waist, which is from Mozi's Love for All. In the past, King Chu Ling was a gentleman with a thin waist, so the ministers of the King Ling all took a meal as a festival, threatened to rest and then took it, helped the wall and then got up.
Once upon a time, King Chu Ling liked men to have slim waists, so a group of ministers in the DPRK were afraid to eat more for fear of losing their favor. They ate a meal every day to control their waists. Hold your breath first, then tighten your belt and stand up against the wall. By the next year, the civil and military officials of the Manchu dynasty were all black and yellow.
