The Sadness of Kaifeng

Kaifeng, historically known as Tokyo, Daliang, and Bianjing, is a famous historical city with rich culture, comparable to Beijing, Nanjing, and Xijing (Chang'an), the ancient capital of the 13th dynasty. So far, Zhao Kuangyin's Chenqiao mutiny, the strategy and classics of wearing a yellow robe and releasing military power over a glass of wine have been widely circulated among the people. There are also theories that Zhao Kuangyin and the later Zhou emperor Chai Rong were disloyal and were traitors.
