Cuihu Park is known for its emerald waters on all sides, verdant bamboos year-round, and verdant willows in spring and summer, earning it the name "Cuihu."
In 1919, Tang Jiyao constructed a long east-west causeway, named "Tang Causeway." The two embankments intersect at the central island, dividing the lake into four sections. Cuihu Park includes attractions such as Shuiyue Pavilion, Haixin Pavilion, Jiulong Pond, Guanyu Tower, Lianhua Zen Temple, Southwest Island, and Bamboo Forest Island. Its distinctive landscape features a scene of "a world of ten acres of lotus and fish, and half a city of willows and Buddhist pavilions."
Cuihu Park's two famous willow embankments intersect in a cross shape, dividing the lake into four sections. The north-south horizontal causeway is called "Ruan Causeway," and the east-west longitudinal causeway is called "Tang Causeway." The intersection of the two causes forms a small island in the center of the lake, with the Central Pavilion as the main axis, forming the central tourist area.
On November 12, 1985, hundreds of seagulls suddenly descended upon Green Lake, surprising visitors. Some threw snacks to the birds, and they scrambled for the food. A few days later, the flock swelled to several thousand, and even more people gathered around the lake. Vendors began selling food, and gull watchers, vying for it, tossed it into the air, drawing the birds to the feast, much to their delight. Since then, every October to April, tens of thousands of seagulls have flown from the north across thousands of mountains and rivers to Kunming for the winter, becoming a major spectacle and attracting countless tourists for birdwatching.
