Yao Shun Chan let.
Legend has it that in ancient times, Emperor Yao reigned for more than 70 years and was ready to abdicate when he was old. He consulted the "Four Mountains" on the issue of the heir, and the "Four Mountains" promoted Shun to the throne. Yao conducted a multifaceted investigation of Shun, and finally gave the Zen position to Shun. Later, Shun also took the form of Tongxiang Zen located in Yu.
Yao and Shun solicited the opinions of everyone in the abdication of the throne, and did not serve their sons and "selected the virtuous and able", which is Zen Rang.
The legend of Chan Rang reflects the situation of military democracy at the end of primitive Chinese society. At that time, several clans formed tribes, and tribal chiefs were promoted; A number of tribes form a tribal alliance, and the chiefs of each tribe elect the leader of the alliance. The "Four Mountains" are the tribal chieftains who participated in the Saki Alliance, and Yao, Shun, and Yu are the leaders of the Alliance. It can be seen that Chan Rang is a system of determining the heir to the leader of the tribal alliance through democratic promotion and investigation.
With the gradual development of private ownership, Chan was finally replaced by a hereditary system. Legend has it that during Yu's reign, everyone elected Gao Tao as the heir. Gao Tao died early, and everyone elected Boyi as his heir. However, after Yu's death, his son Qi seized the throne and became self-reliant, and the Zen system was abandoned from then on.
Tang Yao passed the throne to Yu Shun, and at the same time passed the four words of Yun Zhiji; Yu Shun passed the throne to Dayu, and at the same time passed on the sixteen-character heart of Yao Shun (referred to as the Chinese heart method), which became the national philosophy of 5,000 years of governance.
