What are the pain points of renting a house?

After graduating from college, I went back to Nanjing. Because of my hobby, two other little girls and I rented it near Laomendong for a year. I can't wait to move out after one year. A lot of problems, I was impressed that I didn't clean it. The original wooden floor was covered with dust. Once a girl ate instant noodles. I don't know why I wanted to see if she threw it, so I didn't help her throw it. As a result, I was able to move the instant noodle box to fill it the next day without throwing it away. I wasn't here during the period, and when I came back, the instant noodle box was gone, which was thrown by Miss B! The house expired on February 20, and I moved out within the specified time. A and B moved out on March 20th, so the house deposit was gone. They didn't tell me at first, but I didn't know until I heard that the deposit was not refundable.
