The strict identity was explained as soon as it appeared. In the ninth chapter, the author wrote that "strictness is what Baoyu needs most".
Yan Yan's identity is unusual, and Baoyu's attitude towards Yan Yan is also different. The ninth time, the urchin made Yan Ming in the school a catalyst to promote the debate and hit people. Li Gui, Baoyu's great servant, scolded him afterwards, but Baoyu defended him. "Everyone sees Yan Ming bullying me. Is he not suitable for me? " They are fighting and smoking tea "; The 19th time, Yan Ming and a girl named Wan'er were caught in the study. Baoyu just reprimanded Yan Ming for not reporting him. Baoyu is going to attack others later, fearing that he will be blamed for this. Baoyu comforted: "Baoyu smiled and said,' I'm here.' "; The thirty-ninth time, Baoyu heard a girl named Mingyu who was spun up by Granny Liu. In order to find her statue, one day Baoyu sent Yan Ming to find it. Yan Ming came back and said that he couldn't find it. Baoyu spat at him and scolded him again. Yan Ming is of course wronged. The author wrote here that "Baoyu saw that he was in a hurry and was busy comforting him." Yan Yan is highly valued by Baoyu, and the friendship between Baoyu and Yan Yan also shows that Yan Yan's identity is really extraordinary.
