It is mentioned in the book that the Buddha agreed that the people of the Old Nine Gates must take turns to guard bronze doors's secret and change it every ten years. However, except for the Zhang family, no one else in Laojiumen kept this agreement. Therefore, the zhangs' have been solely responsible for guarding bronze doors's secret.
If Lao Jiumen kept his promise, it would be Wu Xie's turn to stay in bronze doors for ten years in 2005. However, Zhang Qiling, who has a deep affection for Wu Xie, decided to replace Wu Xie in the face of Wu Xie in order to keep the position of the Wu family for ten years. And agreed that ten years later, Wu Xie would come to Tongmen in Changbai Mountain to pick up Zhang Qiling and go home.

Extended data:
In "Notes on Grave Robbery: Yinshan Mountain in Gu Lou", Wu Xie and Fatty lead Zhang Qiling to Bajiao Garden to continue searching for lost memories, and the mystery of his life seems to become clear. After entering Zhang Gu Lou, he recalled and ended everything he didn't know.
Tell Wu Xie that he is the gatekeeper guarding bronze doors (Zhang Jia and Lao Jiumen agreed that everyone would take turns guarding bronze doors, but none of the old Jiumen kept their promise to guard bronze doors, all of them were guarded by Zhang Jia, and it was Wu Xie's turn this time). After stunning Wu Xie, he entered the "ultimate" (in bronze doors) to replace Wu Xie as the gatekeeper for ten years.
Give Wu Xie another ghost, and tell Wu Xie that if he remembers him ten years later, he will come to Changbai Mountain with a ghost, and maybe he will meet him at the door and take his place.
