A paulownia tree in the Yuxiang compound is the concern of Yu Sui'er when she grows up. It is a sacred tree and was given by the gods three hundred years ago when the ancestors of the Yu family performed well in making fire. Nowadays, Yu's family is sparse, and Juanjuan Junshu has taken away Yu Suier's grandfather, father and younger brother. Yu Sui'er also misses her unrelated brother Xu Xuan. Xu Xan is not from Yuxiang, and his life experience has always been a mystery, but Yu Sui'er is still willing to get close to him. A hundred years later, the war subsided, and Yuxiang had long been trampled by cavalry. The two reunited at a Buddhist shrine in the desert, and from then on the two lonely souls embarked on a journey home.
Purpose: Feelings of family and country
