Xingyun Lake (Xīng yún Hú 星云湖) also known as Jiangchuan Sea (Jiāng chuān Hǎi zi 江川海子), is a plateau lake in Yunnan Province, southwest of China. It is laceted in Jiangchuan County (jiāng chuān xiàn 江川县). The Xingyun Lake and the Fuxian Lake (fǔ xiān hú 抚仙湖) are separated by a mountain and linked by Haimen River (hǎi mén hé 海门河). The glistening light of the waves is charming and attractive. During the cloudless night, the bright moonlight shines upon the lake, looking like numerous stars glinting and falling into the lake. It also looks as brilliant as the cloud. So the lake get its name Xingyun Lake (literally Star-Cloud Lake).

Known as one of "the biggest and most splendid cave in Asia", the Swallow Cave (yàn zǐ dòng 燕子洞) Scenic Region is located in the mountains 30 km east of Jianshui (jiàn shuǐ 建水), and consists of a dry cave, a water cave and a 30,000-square-meter natural forest, with a total area of 100,000 square meters. Every year between spring and summer, thousands of swallows will fly here from Malaysia, building nests and giving birth to and raising young swallows. Thus it is named "the Swallow Cave". The local environment is a perfect dwelling for swallows because steep cliffs make it impossible for mice and snakes to come up, and bushes and grassland outside the cave help produce insects that provide abundant food for swifts. The special ecosystem makes a grand scene-"the gathering of thousands of swallows".
