Covering an area of 23,000 square meters, the Temple of Universal Peace (Puning si), is the furthest north of the eight remaining outer temples of Chengde. The temple has also in its time been known as the Big Buddha Temple (Dafo si).

This temple, like many in Chengde, is designed mainly in Tibetan and Han styles, with various halls including the Gate Hall, the Bell and Drum Towers, a Stele Pavilion, the Hall of Heavenly Kings and the Mahavira Hall. The temple was built in 1755 to commemorate the Qing Dynasty victory over a troublesome Mongolian force, and a stele, in front of the main gate commemorates this.

The 36.75 meter high Mayana Hall is where most people here tend to head. Inside here, the 22.23 meter high, 110 ton statue of Avalokiteshvara (Guanyin in Mandarin), is the largest wooden statue in the world. Made with five different types of wood (pine, cypress, elm, fir and basswood), this enormous statue is one of the few remaining wooden Buddha in China. The rest of the halls also contain a variety of interesting, though smaller statues.
