Santan silver moon Island is the largest island in the West Lake, with beautiful scenery and quiet scenery. Also known as Saint Tan Yingyue, it covers an area of 60,000 square meters. Therefore, the island is known as the "Little Yingzhou", with beautiful tree shadows, elegant gardens, rich cultural context and graceful appearance, ranking among the ten scenic spots in the West Lake, especially in the Mid-Autumn Festival, when the moon in the air, the moon in the water, the moon in the tower and the "bright moon" in the hearts of moon watchers shine up and down, eager to fly.

Hu Xinting is in the middle of the West Lake, smaller than San Tan Yin Yue and bigger than Ruan Gongdun, and is collectively called "Penglai Island"-Hu Xinting is called "Penglai" and San Tan Yin Yue is called "Yingzhou". Ruan Gongdun is the "abbot". During the Song and Yuan Dynasties, there was a temple in the middle of the lake, which fell down later. In the Ming Dynasty, Sun Meng, the magistrate, built Lu Zhenting, which was later changed to Qingxi Pavilion, the predecessor of Huting. Looking at the pavilion in the middle of the lake, the lake is bright and the mountains are like green curtains, which is known as "the middle of the lake is flat" On the pavilion, Emperor Qianlong inscribed the inscription "Looking at all kinds" and the couplet "The lake is far away, the waves are high, and the mountains promote the water depth".

Ruangongdun is a green island in the West Lake. According to records, since the fifth year of Jiaqing in Qing Dynasty (A.D. 1880), Ruan Yuan, the governor of Zhejiang Province, presided over the construction of Ruan Gong Dun, an island made of dredged silt. "Ruandun" is Ruan Gongdun. In order to commemorate his contribution to the development of Zhejiang culture, the preservation of ancient documents and the management of the West Lake, the island was named Ruan Gongdun. Now floating on the sparkling blue waves, it is one of the three famous islands in the West Lake. Because of the soft soil, it is not suitable for building villas, and it has been abandoned for more than one hundred years. 1982, in order to develop tourism resources, more than 1 1,000 tons of soil was added to this small island with an area of 8.5 mu, and the surrounding rocks were reinforced. The capital construction covers more than 240 square meters, including "Yiyun Pavilion", "Yunshuiju" and "Small Building Around Bizhuang", and then a fishing area and "Around Bizhuang" will be established to form a distinctive "bamboo building with green trees and flowers". Because of the blue waves outside the island and the lush vegetation on the island, it was named Huanbizhuang, known as "Soft Pier Huanbi".
