Baiyukou scenic resort is located on the west bank of Dianchi Lake, to the southeast of Guanyinshan, 38 kilometers away from Kunming City. It is a small peninsula protruding into the lake, and is in harmonious coordination with the distant cape of Guanyinshan that also stretches into the lake.

The scenic resort is embraced on three sides by cliffs covered with dense forest, while the other side faces the immaculate and mirror-like expanse of the lake, offering the visitors a quiet and beautiful place for relaxation. The bay of the lake in that locality is renowned for teeming with a kind of small white fish called 'baiyu' in Chinese, hence the name of the place - Baiyukou (the White Fish Mouth). 

Late is the Ming Dynasty, the famous Chinese traveler Xu Xiake toured Dianchi Lake and landed right on Baiyukou. In his travelogue he wrote: '...A hot spring was found at the foot of the mountain, and the people on boats were lured to land for baths...'

 In 1922, the first year of the Republic of China, a high-ranking official Yu Enxi chose the place for his villa. It is a 3-storey stone building, with hills behind and the lake in front. The villa was luxuriously furnished, and a hot-spring bathroom was built separately on the right side of the building. On the east and south sides of the stone building, there are beautiful gardens. These gardens are separated from the lake by a pond and a long embankment on which weeping willows stand neatly. The glimmering water of the pond is dotted with lotus flowers, and occasionally, fish shuttle among the ripples. Around the pond there are Chinese flowering crabapples that flourish into thick woods. In front of the stone building is a meadow in which junipers are planted. Precious Yunnan flowers such as camellia, azalea, magnolia and sweet osmanthus dot the carpet-like grass with a splendor of colors. On the stone embankment built to the east of the building to divide the pond from the lake, weeping willows are leisurely rinsing their hair, making the place a most lyrical and picturesque one.

In 1953, the Provincial Worker's Sanatorium was built at Baiyukou. Later, a pier was built to the south of the villa for tourist boats. Stretching into the lake, the sanatorium is also a good place to view the scenery. Farther on to the south of the lake villa, there are gardens with pavilions and arbors typical of the styles of the minority nationalities in Yunnan Province. The sanatorium is located to the west of the pavilions and arbors, and is composed of groups of gardens, buildings typical of south China and tall buildings peeping out from rows of magnolia, pine and cypress trees.
