能帮我看下这段话有什么语法错吗?如何改正
Another experience is related to my bad experience. I booked a room in a hotel because one of my foreign friends came to visit me. But when we walked to the room, he seemed very nervous and surprised. He told me he didn't want this room and hope to change for another one. Hence, the hotel changed other room for him. After then, my friend told me that Room No.13 was unlucky to them. Indeed, I searched the Internet to find out of information about it. I felt upset and sorry to my friend. Thus, it is possible to understand and value other cultural identity in order to avoid mistake
