The Yanqi Lake is located on the edge of the Great Wall at the foot of Yanshan Mountain. Flocks of wild geese often come to live in the lake every spring and autumn, hence the name. The 2014 APEC Economic Leaders' Meeting and the 2017 Belt and Road Forum for International Cooperation were held here, and the Yanqi Lake became the focus of worldwide attention.

The Yanqi Lake has a flat terrain and broad water area, which is very suitable for various water and land entertainment projects. It is a famous tourist scenic spot and water park in the suburbs of Beijing. After the APEC meeting, a comprehensive guided tour system, slow-moving system and cycling system were built with the Yanqi Lake as the core in the area of 21 square kilometers. Sightseeing cars, shuttle buses and ferry boats are in place. Tourists can take a boat tour around the lake.
