Introduction to Jiaoshan Lake: Jiaoshan Lake was transformed on the basis of the original Jiaoshan Reservoir. With the Quanxue Platform as its cultural support, it highlights the green landscape and has become an important window to showcase the development of Tongshan tourism. "Jiao" changes to "Jiao", and with just one word difference, the whole realm comes out. "There are so many beauties in the country" is not only a dream and goal, but also full of governance consciousness and humanistic feelings that will change the world. It took Tongshan more than a year to complete this initiative and realize the beautiful wish of "a flat lake emerging from the mountains".
