Zhu Yuanzhang asked Liu Bowen if Li Shanchang was not the prime minister, who could be? Liu Bowen was silent, and then Zhu Yuanzhang mentioned this person, and Liu Bowen replied: No, this person has the talent of a prime minister, but he does not have the amount of a prime minister. However, Zhu Yuanzhang did not believe in evil, or let him become the left chancellor of Zhongshu Province, and squeezed Li Shanchang aside, but after this person took the throne, he was arbitrary, coupled with the conspiracy and calculation of Li Shanchang and Hu Weiyong, it was not long before he was beheaded by Zhu Yuanzhang, verifying the accuracy of Liu Bowen's vision, so who is this person?

His name was Yang Xian, a native of Taiyuan, who later lived in Nanjing, and at the end of the Yuan Dynasty, the people were not happy, but his family was very wealthy, because his father was an official in Jiangnan, so he received a good poetry education from an early age and was familiar with the history of the scriptures. When Zhu Yuanzhang led his troops to capture Nanjing, Yang Xian went to defect, and it was wartime, zhu Yuanzhang urgently needed a batch of documents to deal with marching documents, letters, and texts, so he arrived at a very good time and was appointed by Zhu Yuanzhang as a shogunate document.
He was a man of erudition and strong memory, zhu Yuanzhang made it quite easy, and gradually cultivated into a confidant, allowing him to engage in intelligence work. Under the circumstances at that time, Zhu Yuanzhang was surrounded by strong enemies, in order to survive in the cracks, it was inevitable to deal with other tyrants, so Yang Xian came in handy, Zhu Yuanzhang let him go to the surrounding areas many times, to Fang Guozhen camp 2 times, to Zhang Shicheng's army 3 times. Because he was clever, knowledgeable, and courageous enough, he could complete the task well, and Zhu Yuanzhang trusted him even more.
After Zhu Yuanzhang founded the Ming Dynasty, the imperial court was divided into two major factions, one faction was the Huaixi Party headed by Li Shanchang, these people were Zhu Yuanzhang's compatriots, and the old Zhu Had the most to contribute to the world. The first faction was the Zhejiang Eastern Party headed by Yang Xian. It is worth mentioning that Liu Bowen is also a person from the eastern Zhejiang region, but he is very smart and has never been involved in party strife, but with Zhu Yuanzhang's suspicious personality, that is, old Liu did not participate in the Zhejiang Eastern Party, and he would also suspect that Old Liu was the Eastern Zhejiang Party.
In order to balance the situation, Zhu Yuanzhang did not want Li Shanchang's family to be dominant, so he deliberately supported Yang Xian and fought with him. However, he still wanted to consult Liu Bowen's opinion, so he asked Liu Bowen who could replace Li Shanchang, and then Lao Zhu asked: Yang Xianxing is not OK. Liu Bowen replied truthfully: He has the talent of a prime minister, but he does not have the amount of a prime minister. Unfortunately, Zhu Yuanzhang did not listen to Liu Bowen's words, but still transferred Yang Xian to Zhongshu Province to serve as the governor of Zhongshu Province, and the next year he was promoted to Zuo Cheng.
However, when Yang Xian arrived at this position, he was a bit drifting, and he fought with Li Shanchang and Hu Weiyong all day long, and his impetuousness brought disaster to himself. As a result, he was killed by Zhu Yuanzhang in the same month, which was a pity. Yang Xian's death was to blame three people, one of whom was himself, and when he reached a high position, he was oblivious and too eager to succeed. Another is Li Shanchang, who deliberately dug a pit and waited for Yang Xian to jump in without reminding him. The last one was Zhu Yuanzhang, who liu Bowen obviously reminded him not to let Yang Xian be the prime minister, but old Zhu did not listen. These three people finally put Yang Xian to death.
