Who was the first benevolent emperor of a feudal dynasty? The fourth emperor of the Han Dynasty, Liu Heng, the Emperor Wen of Han, was also! He was diligent and thrifty, abolished corporal punishment, and was still one of the twenty-four filial pieties, honoring his mother Empress Bo, or leaving the world one step ahead of his mother, and before he died, he also told his son Liu Qi to be filial to his grandmother! It is such a benevolent monarch who even has a little-known cruel side, in order to successfully ascend the throne, killed his brother's three sons, similarly, for the sake of the eldest son Liu Qi's crown prince, he actually killed his other three sons, all said that "tiger poison does not eat children", although there are many animal fathers who killed their sons in history.
For example, Wang Mang, Shi Hu, Sun Quan, Li Shimin, Li Longji, etc. have all done this, but who would have thought that the emperor, who could even be touched by outsiders, would actually do such a thing with a human face and a beastly heart! The emperor before Emperor Wen of Han was Emperor Shao, but he was a child, who was killed by Lü Hou, and the emperor who went before him was Lü Hou's son Liu Ying of Han Hui, although Liu Ying was a Ming Jun, but his mother Lü Hou was too domineering, and finally died of depression! Finally, the chancellor suggested that Liu Heng, who was the acting king in the field, be taken back to succeed to the throne, so Liu Heng was hit by a pie that fell from the sky and became the emperor!
However, after Liu Heng became emperor, he was afraid of growing branches outside the festival, so he got rid of liu wu and three other nephews of Liu Wu, the prince of Liangxiao, and strangely enough, Emperor Wen of Han also had a son named Liu Wu, which was so strange! Later, in order to make his eldest son Liu Qi (later Emperor Jing of Han), he was able to become the crown prince smoothly, and he actually designed his three sons to disappear from this world, which was really hard to believe!
