Amidst lush green mountains and clear waters, One Minute in Changsha Season 2 invites you to explore Shiyan Lake, located at the junction of Changsha, Zhuzhou, and Xiangtan, and experience the lakeside spring charm in the heart of the city’s green space. Surrounded by crystal-clear waters, Shiyan Lake boasts a forest coverage rate of over 98%, with an abundance of negative ions, earning it the reputation of a natural oxygen bar. The lake is steeped in history, named after the discovery of Shiyan fossils. In spring, young people stroll along the lakeside, challenge themselves on the sky glass bridge, and gather at night for camping and bonfires, singing and enjoying the scenic beauty of mountains and waters.

Shiyan Lake is situated at the “core” of the Chang-Zhu-Tan Ecological Green Heart, covering an area of 528.32 square kilometers. It is the first city cluster green heart to be explored in China and is the largest in the world. Known as the "lungs of the city," it also serves as the ecological backbone of the Chang-Zhu-Tan Metropolitan Area. In recent years, Hunan Province has vigorously promoted the integration of Changsha, Zhuzhou, and Xiangtan, developing a series of connectivity projects, including direct highways, bi-directional rail transport, and collaborative "outlying zones." With joint efforts in establishing schools and hospitals, these initiatives continue to advance the integration of the three cities, providing a platform for coordinated industrial development.

The integration of these three cities is further emphasized at Shiyan Lake, located at the gateway to the Chang-Zhu-Tan Metropolitan Area. Here, the principle of "lucid waters and lush mountains are invaluable assets" is being actively practiced, propelling the region's ecological civilization. Shiyan Lake’s development is paving the way for the "core" to drive the integrated growth of the Chang-Zhu-Tan metropolitan area, offering a new model for sustainable development.
