The Dayan Dynasty was founded for more than 160 years, and it was passed down to the current emperor - Emperor Yan Xiao Chong, the eleventh generation of emperors. Dayan built a country based on commerce and ruled the world with culture. The founder of Dayan was originally a salt merchant. He was well aware of the benefits of commerce. Therefore, at the beginning of the founding of the country, he established the national policy of "trading trade and benefiting workers." The status of merchants was far superior to that of the previous dynasties, but they were still restricted by the old order of "scholars, farmers, industry and commerce" - merchants can be rich, but it is difficult to enter the temple.
