CHONGQING (CQNEWS) -- One year ago, the water quality of Yubei Bijin Lake was in a turbid and low-transparent state, at times giving out a rancid smell. Now, the foul smell has disappeared from the lake, and the water is clear as crystals. A small underwater “forest” has even emerged at the bottom of the lake.
