The murderer of the second act of the reincarnation hotel

The following is the key evidence, murderer, timeline, complex analysis, reasoning logic and complete answer of the ever-changing detective "The Hotel of Samsara".

Everyone's room numbers are: Chen Daoqian 260 1, Si Forgot Book 2062, Bai Xixia 2603, 2604, Chen Shangxue 2605 and Chen 2606. First of all, from Chen's script, we can know that he lives in a room near the end of the corridor, and the room number is 260 1. From the picture, we can determine the location of 260 1 (there are only two rooms at the end of the corridor, one is 2606 and the other is 260 1).

According to Chen Shangxue's script, Chen Shangxue lives in a place where Chen Daogan can't be seen, so Chen Shangxue's room is in 2604~2606. The script of "Forgetting Books" mentioned that he helped a woman with her luggage. According to the information, Si Forgotten Book helped Baixixia. Judging from Si Forgotten Book's script, Baixixia is next door to him. According to Bai Xixia's script, there are two boys in her position. Now it is known that Chen Daoqian is at 260 1 and Chen Shangxue is on the other side, so the room where Siwangshu and Bai Xixia are located can only be in Chen Dao, otherwise Bai Xixia can't have two boy neighbors. Bai Xixia heard the sound next door in the room, so Bai Xixia's room is 2603 near the hall, and the room where she forgot her books is 2602 in the middle.
