Fu Su, the eldest son of Qin Shihuang, was a political visionary among the rulers of the Qin Dynasty. He believed that the world was uncertain and the people were uneasy, and opposed the policy of "burning books to bury Confucianism" and "emphasizing law and justice", so he was demoted to Meng Tianjun's army by Qin Shihuang. After the death of Qin Shihuang, Zhao Gao and others were afraid that Fu Su would take power, so they forged letters, accusing Fu Su of being "unfilial" and "wasting too much time", and "outspoken" during his stationing troops in the frontier and Montaigne, forcing him to commit suicide. Qin Shihuang's eldest son, because his mother was a native of Zheng, liked to sing the local popular love song "There is a millet on the mountain", so the first emperor named their son "Fu Su", which was an ancient description of the lush foliage of trees, so Qin Shihuang named it after it, obviously placing infinite expectations on this son. When he was young, Fu Su was witty and intelligent, and he was born with a compassionate heart, so he often ran counter to the tyrannical Qin Shihuang in political views. The first emperor paranoid that this was caused by Fuxi's cowardice, so he decided to let Fuxi help General Meng Tian build the Great Wall of Wan Li to resist the Xiongnu in the north, hoping to cultivate a resolute and brave Fuxi. Several years of exploration beyond the Great Wall really set Fu Su apart. He took the lead, was brave and good at fighting, and made outstanding achievements. His keen insight and excellent command ability have amazed many frontier generals. He loves the people like a son, treats others with humility, and wins the love and admiration of the broad masses of the people.
