People play in the free giant swimming pool. The pond used to be a contaminated place. In 2016, local people called for capital contributions to renovate the village pond into a huge swimming pool for free.

Local people call it a water park.

Mr. Nguyen Phi Hau, 59, is the founder of Duong Lieu Commune Swimming Club, had the idea of transforming the polluted pond into a free "pool".

On summer days, the swimming pool serves hundreds of people. 

Thanks to the pond, all children in the village can swim well.

This is not only a place for children to bathe and play but also a useful way for elderly people to cure disease. 

The water is replaced once a year but the pond is cleaned daily.
