From the youngest son of a scholarly family in Bianliang City to a slave whose family was broken and who was slaughtered by others, he relied on his outstanding ability and wisdom to get through many obstacles until he was appreciated by Kublai Khan, the founder of the Yuan Dynasty. He broke the situation with forbearance and power, was good at assisting Mongolian politics with Han law, worked hard to promote the integration of Han culture and grassland culture, and was committed to protecting the classics and techniques of the Central Plains. Always taking peace of the people as the bottom line, we have achieved personal political repayment and class transcendence.
