I believe that many people have watched the TV series "Supreme Red Face", in which the love between Wu Meiniang and Li Junxian is touching. However, in real history, Li Junxian and Wu Zetian did not have much intersection, on the contrary, Li Junxian carried a pot once because of his own name Wu Zetian, and was eventually wrongfully killed by Li Shimin.
Li Junxian, who has learned martial arts since childhood, is familiar with the art of war, and has great courage. During the war and chaos at the end of the Sui Dynasty, he first joined Wagangzhai and later became a lieutenant of light vehicles under Li Yuan, and then he has been serving Li Shimin, and has made many military achievements in the process of Li Shimin's southern conquest of the Northern War. Li Shimin was proclaimed empress dowager, and naturally he would not forget this meritorious minister and made him a general of the Left Wei Dynasty.
After Li Shimin became emperor, there was a rumor circulating in the folk: the heroine Wu Wang has the world. Wu Naturally here is talking about Wu Zetian, but Li Shimin didn't care about this because he loved Wu Zetian. At a banquet, Li Shimin accidentally learned that Li Junxian's nickname was "Five Niangzi", and at that time, Li Junxian held the position of General of Wu Wei, so Li Shimin naturally believed that the word "Wu" referred to Li Junxian. So Li Shimin became murderous, found an excuse to put Li Junxian to death, and destroyed Li Junxian's entire family.
