Introduction to Bihe Pavilion: In the southeast corner of the square, there is a four-corner pavilion called Bihe Pavilion. On both sides of the railing are written vertical lines a poem by Yang Wanli, a great poet of the Song Dynasty, "The lotus leaves touching the sky are infinitely green, and the lotus flowers reflecting the sun are uniquely red." Climbing up to the pavilion, you will see thousands of acres of lotus fields with rolling blue waves and thousands of colorful lotus flowers.
