Guan Xiaozheng and his mother had a series of activities on Friday night. They first debated the number of episodes in Journey to the West, then played military chess, followed by Guan Xiaozheng repairing a damaged gyro handle and playing gyro with his mother. At night, they were awakened by the noise of upstairs decoration and tried various methods to cope, including peeling walnuts and making passion fruit sauce. In the end, they called the police and the noise stopped when the police arrived. A few days later, new neighbors moved in, but their arrival seemed to have had an impact on Guan Xiaozheng's pomegranate tree. Pomegranate flowers began to fall abnormally, and Guan Xiaozheng and his mother suspected that it was caused by the new neighbors littering cigarette butts, and decided to investigate further.
