According to Beijing News, the building was a breeding base for the Chinese giant salamander and was approved by local agricultural authorities when the county had a vigorous expansion in the Chinese giant salamander breeding industry. /CFP

The Chinese giant salamander requires a lot of water and likes to live in streams in caves, so the plant was built there, Beijing News cited the owner, a man surnamed Shang, as saying. /CFP
