Introduction to Biyun Water Pavilion: Biyun Water Pavilion is the most beautiful landscape in Yanshan Garden. Willows are planted on the lakeside and lotus trees are planted in the lake. There is a two-story and some three-story large water pavilion in the lake, which is shaped like a boat, hence the name "Biyun Lake Boat". Climbing the boat on Biyun Lake to watch, I saw strands of weeping willows, dots of red lotus, graceful boats, and reflections of green peaks, which was so beautiful.
