Zhu De once commented that Susan "has three fathers and sons, all of whom are great writers. Poetry and fu have been handed down from generation to generation, and the proportion of flying moths and eyebrows is high. " Both father and son are quite successful, so what contribution does Su Zhe make as Su Shi's younger brother? How is history evaluated?

What are Su Zhe's main achievements?

In the fifth year of Yuanfeng (1082), the river still overflowed after returning to the north. In September of the first year of Yuan Dynasty (1086), the court ordered the secretary to supervise Zhang Wen's visit to Hebei Water Affairs. In November, Zhang Wen asked him to open a straight river in Nanle Daming, and sign the river to divert water into Suncun, in order to solve the problem of Beijing's downward movement, and the discussion of returning to Hedong resumed. Ministers Wen Yanbo, Lu Dafang, Wang, Wang Tuan, Du, Wang Xiaoxian, Wu, Li Wei, etc. Everyone was urged to return to Hedong. On the right, Fan Chunren, Su Zhe, Zeng Zhao, Zhao Zhan, Fan Bailu, and Hu advocated maintaining the northward flow and opposing retreating from the river. In June of the third year of Yuan Dynasty, the emperor wrote a letter saying: "The Yellow River did not return to its original road, and it was ultimately a disaster for Hebei. What Wang Xiaoxian and others discussed was that they tried to promote the service, but they couldn't win it. They should continue their work and materials, and they will definitely go back to their old ways. The three provinces and the Privy Council will quickly implement it through consultation. " In the face of the trend of accelerating the retreat from the river, Su Zhe strongly opposed it, and said to the effect: "After years of discussion, there are 20,000 soldiers and more than 300,000 piles. Where is the disaster, the people secretly sigh. " "Xiao Wu burst into the ground today, Sun Cun opened and his feet were limited. Not only can't return to the river, but also can't divide water. The nature of the Yellow River is that it flows when it is urgent and silts when it is slow. There is no tendency to be anxious about everything. Why should the two rivers run in parallel? Even if the two rivers are parallel, the embankment will be twice as expensive. " In the process of dredging, he refuted three theories, namely, "the imperial river failed", "the flood in northern Hebei was harmful, and public and private losses" and "the river migration was impermanent. In case it entered the sea from the border of Qidan, the border defense was unprepared", and he strongly advocated stopping the war of returning the river. In the first month of the fourth year of the Yuan Dynasty, the court issued a decree to stop returning the river and repair the restored river; In July, the Nangong in Jizhou was in critical condition, but the water superintendent still insisted on the eastward flow or "two branches" to eliminate evil. In August, Su Zhe added, "At the turn of summer and autumn, there are frequent summer rains. The river surges out from the shore, from Suncun to the east, covering every year. However, Li Jue and the river envoys were in a state of confusion. In the name of dividing water, they wanted to send the river proposal back, so the water supervisor made peace with them. When the river surges, don't ask for it. Is the minister happy to hear that it suits him? " "I want to hurry and group. The water potential in Guan Xu is rising according to the old practice for many years. Because it overflowed to the east, it introduced the old road to solve Beijing's worries. If the old dike is broken, repair it slightly to avoid its overflow. As for talking about the river, entering an appointment, etc. Nothing will succeed until the river is settled. " In February and September of five years at the end of Yuan Dynasty, Su Zhe twice advised to stop the eastward flow, demanding "the crime of bullying and neglecting Wu An and Li Jue", and even warned that "if we don't stop repairing the river, if Li doesn't go, the river won't go downstream, and the creatures in the river will have no peace". However, the center of Empress Dowager Cixi's rule always tends to flow eastward. Although it was intermittent, by October of the seventh year of Yuan Dynasty, most of the rivers had flowed eastward. Shao Shengyuan (1094), "Close the north flow, and the water of the whole river will return to the old road". This time, the Yellow River resumed its eastward flow, but only five years later, that is, in the second year of Fu Yuan (1099), the Yellow River burst in the Inner Yellow River, the eastward flow was cut off, and the mainstream tended to flow northward, still reaching the waters near the Ganning Army. Wu, Jong Li and Li Jue, who actively advocated returning to the river, were condemned by the court and "exiled", ending the third dispute of returning to the river.
