Because August 17th, 215 is the expiration of the ten-year contract, Wu Xie welcomes little brother home. For rice, August 17th is the Chinese New Year.

It is mentioned in the book that the Buddha agreed that the people in the Old Nine Gates must take turns to guard the secrets of bronze doors and change them once every ten years, but no one in the Old Nine Gates kept the agreement except the Zhang family where Zhang Qiling was located. Therefore, the Zhang family has been solely responsible for guarding the secrets of bronze doors.

If Lao Jiumen kept the secret as promised, it should be Wu Xie's turn to go behind bronze doors for ten years in 25

But as Zhang Qiling, who has deep affection for Wu Xie, faces Wu Xie, Zhang Qiling decided to replace Wu Xie to keep the Wu's turn for ten years. And agreed that ten years later, Wu Xie would come to Changbai Mountain and bronze doors to take Zhang Qiling home. Return on August 17, 215.
