Origin and Application

They originated from the temporary and阶段性 (phased) needs for toilets in certain situations. Due to the shortage and inadequate layout of public toilets in cities, the government has placed portable toilets in areas where it is relatively difficult to build fixed public toilets to make up for the deficiency in the number and layout of public toilets. For example, in 2023, portable toilets were gradually installed and put into use in the scenic area along the Yellow River in Lanzhou.
