I don't know if this is true for individual rooms or for all rooms. The first thing I noticed when I opened the door was the smell of sewage coming up from the sewer. It was so smelly that I couldn't bear it anymore, so I went out shopping until very late and went to bed. I don't know why it stinks so much, it really stinks. Then, if I judged it correctly, it should be boogers. I saw a foreign object on the table, so I picked it off with my hands. Then I felt something was wrong, and then I smelled my hands, which really smelled bad and fishy. Ah, I hope it can be improved anyway. It's possible that this problem is just in my room, and I don't know about the others.
