What's the name of Li's son?

Li's sons are as follows: the eldest son, Wang Chengzong of Taiyuan, died young; The second sons, Anlu Wang Chengdao, Hedong Wang Chengde, Wu, Cheng Ming and Julu Wang, were all killed in the "Xuanwumen Rebellion". Li Junxian was a hero of the Tang Dynasty. During the period of Emperor Taizong, Li Junxian successively served as General Zuo Wuwei, Governor of Lanzhou, General Zuo Jian and Huazhou Secretariat. In the era of Emperor Taizong, a book "Secret Records" appeared in the society. The book said: "After the Tang Dynasty III, a female ruler, King Wu, will replace the world." Emperor Taizong called Li and asked him to inspect the matter carefully. Li said to him, "According to the astronomical phenomena, the omen of this matter has been formed. This man has been born, in your majesty's palace. Thirty years from now, she will win the world, and she will almost kill all the descendants of the Tang Dynasty. " Taizong said, "What do you think of killing all those suspicious people in the palace?" Li said to him, "Since this is an act of God, there is nowhere to run. People who should be kings cannot die. No matter how many people you kill, they are innocent. And according to the astronomical phenomena, this man is already in the palace, and he is your majesty's family. In another 30 years, she will be old, and then her heart will be softer. Even if she replaces Tang's world, it may not be too lethal to your descendants. If your majesty kills her now, God will surely give birth to a younger one. This person is young, and his temperament may be more vicious. If so, your majesty's descendants may really be killed. " Emperor Taizong felt that this statement made sense and stopped. But Taizong couldn't let go. More unfortunately, at that time, Li Junxian was General Zuo Wuwei, guarding Xuanwu Gate. At a banquet for military attache, Emperor Taizong made a drinking order so that everyone could say his nickname. In Li Junxian, he said his nickname was "Fifth Lady". Hearing this, Emperor Taizong immediately remembered the prophecy of "the mistress is always in charge". But he immediately smiled: "Which woman can be so brave!" " After Emperor Taizong came down, according to the fief of Li Junxian, he was the Duke of Wulian County, and his official position was General Zuo Wuwei, guarding Xuanwu Gate. In addition, it is also called the Five Lady. Obviously, he is the "female king featuring martial arts". So he gave Li Junxian a severe accusation and killed him.
