Do I need to deposit my bag when I change my Hong Kong tourist card to enter the office?

Don't. According to the regulations of China Hongkong Office, you generally need to take good care of your personal belongings, such as luggage and parcels. You need to keep the parcel yourself when you enter the office, not keep it. If it is necessary to store the parcel, you can consult the office staff about the specific regulations and methods for storing the parcel. In addition, you need to pay attention to and abide by the safety and storage regulations of local public places to ensure the safety of personal belongings.
