In 1988, the People’s Government of Guanma Town and No.1 Construction Company of Jilin City jointly developed the cave. The developed passage stretches 380 metres with a total area of 1,800 square metres.
In 2001, Mr. Ren Haitao from Wahaha Group contracted the cave with a term of 50 years.
In 2003, the cave underwent expansion: the tunnel was extended by 150 metres, and a new entrance was opened while the original entrance was converted into an exit.
An underground river section of about 30 metres was developed for pleasure boats. New natural stalactite formations including the Maitreya Buddha and a waterfall were discovered. The waterfall has a drop of 33.5 metres and is also known as the Hundred-Foot Spring.
The original scenic spots inside the cave have been well preserved. A General’s Memorial Wall was built outside the cave entrance at the site where General Yang Jingyu once stayed.
