There are the following famous sayings:

1. The major events in the world must be united if they are divided for a long time, and they must be divided if they are united for a long time. This is excerpted from "The Romance of the Three Kingdoms·Chapter 1".

2. When two people are of the same mind, their sharpness can break through metal; if they speak of the same mind, their stench is as bad as orchids, from "Book of Changes·Xici 1".

3. Do not seek to be born in the same year, the same month and the same day, but seek to die in the same year, the same month and the same day. This comes from "Single Sword Club" by Guan Hanqing of the Yuan Dynasty.
