In recent days, a group of people in southwestern China's Yunnan province allegedly chose to bathe themselves in Fuxian Lake, one of the largest sources of fresh water in China. In one picture captured by a netizen, an older woman is washing her hair in the lake, a bottle of shampoo set beside her.

Fuxian Lake is one of the few lakes in China with class-I water quality, accounting for 9.16 percent of the country's lake water and 91.4 percent of China's class-I quality lake water. However, the lake has witnessed and even hosted a number of uncivilized behaviors in recent years, after becoming a popular tourist destination. In addition to taking baths, other visitors to the lake have also washed clothes and cars in the lake's waters, and even brought pet dogs into the lake. Statistics show that 3.8 tons of garbage are collected along the lake's shore every year.

Following an investigation, the management office of Fuxian Lake reprimanded the personnel responsible for supervising the lake at the time of the incident and tightened subsequent patrols.
