Introduction to Chengyi Pavilion: Chengyi Pavilion is called a pavilion, but it actually adopts a typical waterside pavilion approach: a platform is set up near the water, part of the platform is set on the shore, and part of it extends into the water. There are rectangular single pavilions built on the platform. It is a monolithic building. Once the eight screen doors on the water side are opened, the scenery outside the pavilion is unobstructed. You can look straight at the scattered buildings and pavilions shaded by flowers and trees, as well as the arched rocks on the east bank and the sparse branches and leaves on the east bank. The hidden Huadian Pavilion is a good place to entertain guests, drink tea, appreciate lotus and enjoy the scenery.
