2. "Yangtze River Culture"-Yugou Bridge. Before the moon comes out, Wangjiang River flows by itself. Suddenly, the west of the city is Guo, and the jade hook hangs in the sky. (Hanging on the Xijiang River and Waiting for the Moon with Li Bai)
3. "Struggle spirit of new city construction"-Bosang Bridge. It's called "fighting to help the mulberry" and "lifting the six purlins lightly" (every Taoist priest in the mountains, Yungong Meng Haoran)
4. "Jiangnan culture"-Moon Pillow Bridge. Jiang Nanyi, the most memorable place is Hangzhou. Looking for laurel seeds in the mountain temple in the middle of the month and watching the tide on the pillow in the county pavilion, when will we revisit it? (Recalling Jiangnan Bai Juyi)
