She gave birth to the eldest son of Tang Dezong Li Shi, who was later named Queen Ruizhen by Li Shi. She is just a girl from Jiangnan, with a kind heart, caring about the country, and being kind to others. During the Anshi Rebellion, she only wanted to stay in Chang'an and advance together with the people, so she was respected by the people of Chang'an. Although there was a general who silently pursued him during the separation, he still insisted on his love for Li Yu.
