I didn't stay in the hotel for 24 hours. Is it illegal for the landlord to throw my things out?

Hotel overdue and throwing things are essentially two kinds of behaviors. If the hotel doesn't move out when it expires, you may have to pay extra rent. The landlord throws things privately, which infringes on your property and needs to bear tort liability.

This can be reflected to the hotel department for compensation.

According to Article 10 of China Tourist Hotel Industry Code, "Hotel room charges are based on' room/night' (except hourly rooms). Charge guests a room/night for one day; If you check out after 12 o'clock and before 18 o'clock the next day, the hotel can add half a day's room charge; If you check out after the next day 18, the hotel can add one day's room charge.
