Liu Che, Emperor Wu of Han Dynasty, was one of the most outstanding monarchs in China's feudal dynasties. During his time, he not only introduced the probationary system and the assassin system, but also enacted the Pui En Order, which strengthened monarchical autocracy and centralized power. He also sent his men to fight against the Xiong Nu, opened up a vast territory and developed the Han Dynasty to a peak period. Emperor Wu of Han had a great influence on the course of Chinese history. However, the Yellow River flooding problem has been in the ancient times of endless, as the emperor of Han Wu Di is how to end the Yellow River flooding problem?

Since the Yellow River broke at Gourd, the downstream area has been flooded continuously for more than twenty years, causing the harvest of Liang and Chu to be bad every year. As the son of heaven, Han Wu Di toured the mountains and rivers all the way after sealing the throne at Mount Tai, and the next year there was another drought. Using the Qian Feng method to make sacrifices, there was still very little rain. So Emperor Wu of Han sent a man to lead tens of thousands of people to plug the gourd break, and went to Wanli Sha himself to seek rain. When he came back he himself went to the river's break and sank the white horse and jade jade biscuit into the river, and also ordered his ministers to carry firewood and grass to fill the break.

Han Wu Di visited the mouth of the Yellow River and sacrificed to the river god, and then composed two songs to beg the river god to let the river return to its old course. The lyrics were poignant and full of compassion and love for the people. After tens of thousands of people's efforts, the gourd was finally blocked, and then a palace was built on top of the riverbank, known as Xuanfang Palace. Built two aqueducts on the north side of the river, so that the water would still flow towards the old channel that Dayu had channeled. From then on, peace was restored to the land of Liang and Chu, and there was no more flooding. Han Wu Di personally visit the decisive action, all this shows that he is a sympathetic to the people, know the plight of the people of the good emperor, understand that the water conservancy is related to the national livelihood of the industry, the politicians can not be ignored for a moment of the truth.
