"I like driving trips. Over the past decade, I had been to Lhasa for three times. What impresses me the most is the city’s sanitation. I give it a thumps-up. I have been to a number of cities. Lhasa’s public toilets not only are the cleanest, but also have its own characters. On city's streets, the two-floor public toilet with Tibetan features has become a highlight. Mirrors and liquid soaps are seen in it. Moreover, instead of odor, the air is filled with a light scent of Tibetan incenses. The public toilets are tidy and clean," said Liu Hong, a tourist from Jiangxi Province.

Urban environment reflects its development. The improvement of sanitation is a critical element. As the civilization construction has been strengthened in urban areas, people's needs for a better life is growing. The sanitation work becomes more important. Here, we appreciate sanitation workers' hard work and dedication towards keeping the city clean for days, months and years.
