Is Yimen Chen a joke?

Because "every pear" and "every pear" are homophonic and unlucky, people in China usually eat every pear.

There is an allusion.

In A.D. 1026, the seventh grandson of Xuanyimen Chen entered the DPRK and gave him a pear and a pigeon. Chen Jing thanked him and immediately ate the pear himself. Injong asked Chen Jing, "Why did you keep it for yourself?" Jing said, "Yimen Chen does not divide pears." Injong nodded appreciatively. Jing took a pigeon home to drink, and more than 3000 people at home tasted it. The messenger asked Jing, "Why does a pigeon taste it together?" Jing replied: "The Chen family feels that the grace is greatly increased, and several generations of good pigeons (together) thank the grace." When the messenger played again, Renzong praised: "Honesty and righteousness."
