After the discovery of high-quality spring water in a place about 8 km away from the city, its officials took an immediate measure to increase the gush amount of spring and played a leading role in carrying out the project.

Many citizens volunteered in the project, thus completing it in a short span of time with two filters installed at the spring.

Now the daily gush amount of the spring is more than tens of tons.

The spring water is supplied to citizens via 10-odd groceries in the city. Seen in every part of the city are stalls serving the spring water to passersby.
