First of all, let's talk about how Xu Shiyun, who was stationed in Liyangcang, submitted to Li Tang, Li Yuan had to thank Wei Zheng who Li Mi brought to Chang'an, and Xu Shixian's annexation was entirely due to Wei Zheng.

Li Mi did not reuse Wei Zheng, so when he left Chang'an for Shandong, he did not take Wei Zheng with him. Wei Zheng was like an item that Li Mi couldn't see, and he felt that it was useless to take it with him when he went out—he threw it aside.

In fact, Wei Zheng was a great person, he had proposed many military strategies for Li Mi, but Li Mi never adopted them...... With Wei Zheng's later performance in the Tang Dynasty, it proves that Li Mi is illiterate and misses Wei Zheng's talent.

Since Li Mi threw Wei Zheng to the Tang Dynasty, he made a lot of contributions to the establishment of the early Tang Dynasty, and was ranked fourth among the "Twenty-four Meritorious Heroes of Lingyan Pavilion", plus the prime minister of the Tang Dynasty, known for his outspokenness. For Chinese, who always likes to talk around mountains and rivers and in the clouds, frankness, a quality that everyone should have in interpersonal communication, has become a personality in him, which is praised...... Because speaking outright often hurts people and makes most people uncomfortable, it has developed the habit of most people to speak in a roundabout way.

When Wei Zheng assisted Li Shimin, they admired each other and became a good story of monarchs and ministers in history. Wei Zheng is also a writer, politician and military strategist who can be put on the table in history. He really stepped onto the stage of history when Li Mi brought him into Chang'an, but this time he did not immediately gain a foothold in Chang'an. When he went out to fight, he fell into the hands of Dou Jiande, a peasant army with a little strength, after Dou Jiande failed, Wei Zheng entered the Tang Dynasty for the second time, and his life really opened, it should be said that his ability to govern the country really came in handy.

That's all for later. In his magnificent life, he had to walk step by step, and every step he took was like stepping on thin ice, and he must have felt dangerous and exciting.

Soon after Wei Zheng and Li Mi surrendered to Chang'an, he recommended himself to Li Yuanmao: "Xu Shixian, as the general of Li Mi's old department, still occupies a large area of land that Li Mi once governed, east to the sea, south to the Yangtze River, west to Ruzhou, north to Wei County, now Li Mi defected to the Son of Heaven, Xu Shiyun himself does not know where to go, I personally went to Liyang, Shandong, to persuade Xu Shiyun to return to the Tang Dynasty." ”

Of course, Li Yuan couldn't refuse Wei Zheng's request, and immediately appointed him as his secretary, arranged soldiers and horses, and accompanied him to Liyang.

Xu Shiyun listened to Wei Zheng's intentions, didn't say a word, and promised to surrender to the Tang Dynasty, I don't know what kind of ecstasy was poured into him by Wei Zheng, a messenger who can speak well, so he surrendered to Li Tang so freely.

And...... Xu Shiyun still moved the heavens and returned to obedience without inviting merit.
