Qingfeng was once a Hero Mountain, also known as "China". After the "September 18th Incident", Wang (nicknamed Wang Laozao) organized his hometown people to resist Japanese aggression here and persisted in the struggle 14 years, making this land truly "China land" that the Japanese have never occupied. In the mid-1960s, during the construction of the Third Line, the state built an arsenal "No.280 Factory" here, specializing in the production of anti-aircraft guns for hitting planes, which played an important role in the struggle against the United States and aiding Vietnam. Today, Qingfeng has become a tourist attraction with its magical beauty. The whole scenic spot of Qingfeng Peak covers an area of about 6.5438+10,000 mu, and the two big ditches are divided into southwest and northwest. The ditch in the southwest is called Wanglaogougou.

There is a very high and steep mountain in Wang Lao's gouge, called Silengzi Mountain. At that time, Wang Lao's gouge led the people to stand on these four stare blankly mountains against the Japanese aggressors. Behind the mountain, there is a natural cave under the cliff. At that time, Wang Laochi stored rice noodles and water in this cave.

In the ditch leading to the northwest, it is the former site of the original "280 Arsenal", and the main attractions are distributed in this ditch.
