Most people have one chance in their lifetime to exchange lives. It cannot be reversed after the exchange. But most people miss this opportunity.

Many years later, Xunxiang sat at the door of the golden house built for her by Huaiying, holding her youngest son in her arms. The dusky forest with white mist is their favorite place. The eldest son followed behind his father holding a sword, both of them wearing smart silver fencing uniforms. The eldest twin girls spread a soft mat, one doing yoga and the other playing the guqin. The little daughter was sleepy and slept in a small wooden bed painted with colorful paint. Xingxiang smiled. This time and space may have been transformed into a mess by her.
