Introduction to Dazhaiding: Dazhaiding has steep peaks, steep walls and many strange rocks. Legend has it that it was the Chinese army’s stronghold that stationed troops in ancient times. There are still ruins such as the village gate, the village wall, and the flagpole nest, which are located on the western slope of the middle section of Yanglangou. There are dense pine forests around the peak, with a wide view and pleasant scenery.
