Can I enter downtown Hangzhou without washing my car?

You can enter downtown Hangzhou without washing your car.

The Hangzhou municipal government has not made specific regulations on whether to wash the car, and not washing the car will not be restricted from entering the urban area of Hangzhou by this factor. At present, the restriction measures include "single and even number restriction" and road congestion restriction. These regulations aim to control the number of vehicles and reduce traffic congestion in urban areas, regardless of whether vehicles need to be washed.

If the vehicle does not violate the relevant laws and regulations such as restrictions, the owner can legally enter and leave Hangzhou.
