Toilet issue is not a small matter, because it affects the life quality of the masses. In recent years, the government of Lhasa City has attached great importance to the "toilet revolution", which is an important livelihood project. Through investing large amounts of money, manpower and material resources, the "toilet revolution" has made great progress in terms of coverage area, distribution density and construction level.
