Legal analysis: you can enter Tianjin, but you must provide negative proof of nucleic acid test within seven days, and you must have a green health code. Otherwise, isolation is needed. The number of six districts in Tianjin is limited. You should pay attention to the time limit for foreign licenses to enter Tianjin. You can't run during the restricted time, otherwise the camera will deduct money along the way. However, if there are no restrictions in other areas of Tianjin, including Binhai New Area, foreign licenses can run at will.
Legal basis: Article 11 of the Road Traffic Safety Law of the People's Republic of China. When a motor vehicle is driving on the road, it shall hang the motor vehicle number plate, place the inspection mark and insurance mark, and carry the motor vehicle driving license with it.
Motor vehicle number plates shall be hung in accordance with the regulations and kept clear and complete, and shall not be intentionally obscured or defiled.
No unit or individual may confiscate or detain the motor vehicle license plate.
