My first thought was the sadness at the end of "The Legend of Two Dragons of the Tang Dynasty". I only knew that Kou Zhong turned into a star in the sky and only wanted to protect Yuzhi for the rest of his life. Yi Nian is a touching performance by Raymond Lam and Li Qian. I don't believe that this ending is the end of the story. It is said that after the "Xuanwumen Incident", two dragons - Kou Zhong and Xu Ziling sacrificed their lives for the throne, and Li Shimin ascended the throne as he wished. Two years later, the Tang Dynasty gradually prospered. Who still remembers the once all-powerful young commander Kou Zhong? Could it be that Kou Zhong and Yuzhi will never see each other again in this life?
