Lin Bu stayed with Xue Zhi for five years. During the whole five years, Xue Zhi was always a prodigal son.
Lin Bu's friends had already tried their best to persuade him, but they were no match for Lin Bu's words: "It's hard to buy a lot of money, but I am happy."
Finally, five years later, Xue Zhi figured it out and came back to find Lin Bu.
The prodigal son turned back, but Lin Bu didn't want it anymore.
