Li Shimin and Empress Changsun had a daughter named Li Jizi. After Empress Changsun passed away, Li Shimin personally raised Li Jizi to grow up. The little princess is very obedient, and Li Shimin regards her as the apple of his eye. Li Zhi and the little princess Li Jizi have been playing since childhood, and the two siblings have a very good relationship. Once, Li Shimin sent Li Zhi out to inspect the fiefdom. After Li Zhi returned, he went to see his father the emperor. Li Qianzi and Li Shimin lived together. When Li Qianzi saw his brother who had been separated for a long time and reunited, he acted coquettishly and said, “Brother is on the same line as the courtiers and cannot enter

Li Zhi quickly hugged his younger sister and cried, saying, “Brother doesn’t want to go to the fiefdom for inspection. Brother wants to come to the inner palace every day to play with his younger sister. According to the “Biography of Princesses and Emperors” in the “New Book of Tang”, Li Shimin watched as Li Zhi held the little princess Li Jizi and cried, “The emperor also cried. During the most intense competition between Li Chengqian and Li Tai, Li Zhi also wanted to fight for the world, but dared not openly. Li Zhi adopted a warm and affectionate approach, using the crying technique to establish a well behaved image in front of Li Shimin.
Li Shimin’s sons, all of whom are either dragons or tigers, have to show their divine abilities to compete for the position of crown prince. When Li Chengqian fell from power, Li Tai became the most popular candidate for the crown prince. Li Tai felt that Li Zhi posed a slight threat to his position as crown prince and warned him to be honest. Li Zhi felt that Li Tai’s warning could be used, so he deliberately appeared worried in front of Li Shimin. Li Shimin asked him what was going on, but Li Zhi refused to say. Li Shimin asked repeatedly, and Li Zhi resorted to crying again, repeating Li Tai’s words to Li Shimin.
Before Li Zhi cried out about Li Tai’s threat, Li Chengqian also told Li Shimin that it was not Li Tai who forced him, and he would not rebel. According to the New Book of Tang, “The Sons of Emperor Taizong,” after listening to the words of Li Chengqian and Li Zhi, Li Shimin said, “Let Tai also stand, and both Chengqian and Zhi die; let Zhi also stand, and Tai and Chengqian have nothing else

After Li Zhi was appointed as the crown prince, his position was not stable, and Li Shimin repeatedly wanted to change the title of Wu King Li Ke as the crown prince. At this moment, Li Zhi resorted to crying loudly again. At that time, Master Xuanzang returned from India to retrieve Buddhist scriptures, and the great master needed a temple to translate Buddhist scriptures with peace of mind. Li Zhi seized this opportunity and cried to Li Shimin, saying, “The Empress Dowager, nicknamed Guanyin Maiden, has been enveloping Guanyin all her life. My children and ministers miss her day and night and want to build a Ci’en Temple to pray for her blessings
Li Shimin was moved by his son’s filial piety and immediately ordered funding to build the Dacien Temple. After the completion of the Dacien Temple, we respectfully invite Master Xuanzang to serve as the first abbot of the temple. Li Shimin personally attended the grand ceremony of Master Xuanzang’s abbot of the temple. Li Zhi seized the opportunity to perform the Weeping Nose Technique in memory of his mother Empress Wende, and as a named disciple, he became a disciple of Master Xuanzang.
Li Zhi’s crying was for two people to see. One is Li Shimin. When Li Shimin saw that the obedient son was still so filial, he authorized Li Zhi to grant amnesty to the world and pray for blessings for the mother. The other one is Uncle Changsun Wuji. Li Zhi wants Uncle to know that you have to protect me, and I am the guarantee of your family’s prosperity and wealth. Li Zhi’s cry had a great effect. Changsun Wuji defended him to the death, and Li Shimin didn’t want to change the crown prince anymore.
