Li is an idiom in China, pronounced as l ǐ sh à ng w m ǐ ng lá i, which means to pay attention to reciprocity in etiquette and treat each other in the same way as the other person treats himself. From Book of Rites Quli Shang.

During the Spring and Autumn Period, Confucius invited his disciples to give lectures at home, which attracted Lu's attention and often went to the palace to give lectures. Yang hu, the manager of Gifford, went to visit Confucius specially, but Confucius made an excuse not to see him. A roast suckling pig was specially left for Confucius. Knowing that Confucius was the most polite, I finally got a return visit from Confucius.
