Yuan Tiangang is a very famous master of geomantic omen in history. His most successful achievement is to predict that Wu Zetian proclaimed himself emperor. Before Ma Zhou became prime minister of the Tang Dynasty, he was very frustrated. He read a lot of poetry books and was proficient in The Book of Songs and Zuo Zhuan, but he didn't meet anyone who could appreciate his talent. Due to lack of talent, Ma Zhou is very sad every day and often drinks to paralyze himself. Finally, Ma Zhou couldn't stand this kind of life, so he went to Beijing alone to find Yuan Tiangang and wanted him to do divination.
This time, after seeing him, Yuan Tiangang said that he was a celestial fairy, and he could have been rich in this life, but he lost his life by drinking all day, and there was not much time left. Ma Zhou was taken aback. Yuan Tiangang told him some solutions, but whether they can be solved depends on Ma Zhou himself. When Yuan Tiangang saw Ma Zhou again, he found that Ma Zhou's complexion was completely different from that when he saw him for the first time 1 time, so he predicted that he would be smooth sailing until he became prime minister.
Sure enough, Ma Zhou finally became the prime minister of Li Shimin. During the Zhenguan period, Emperor Taizong invited hundreds of officials to discuss politics. At that time, an official named Changhe gave more than 20 pieces of advice. According to Li Shimin's understanding of him, this man is not so talented, so he dug Ma Zhou behind his back. Since then, Ma Zhou has entered the official career and has been the prime minister by virtue of his own talents.
