Introduction to Haiyue Gate: During the Northern Song Dynasty, when Mi Fu was a professor of state studies in Runzhou (1089-1091), he built three residences in this beautiful urban forest. "Haiyue Temple" was the first to be built. In front of the nunnery, Mi Fu inscribed the four characters "Heaven opens to sea and mountains", which looks like a rainbow and makes him feel bold when he reads it. These four characters best represent Mi Fu's "awesome spirit" and "economic aspirations" deep in his heart. Therefore, we named the square in front of the "China Mi Fu Calligraphy Park" "Haiyue Square" to show our appreciation for this. The memory of a "Haiyue Manshi". Haiyue Square is mainly composed of three parts: "Park Mountain", "Haiyue Gate" and "Relief Wall". "Park Mountain" is the epitome of the ten-mile long mountain. It is engraved with the six characters "Mi Fu Calligraphy Park" inscribed by Li Lanqing, former member of the Standing Committee of the Political Bureau of the Central Committee and Vice Premier of the State Council; the large stone square "Haiyue Gate" is "Chinese Mi Fu Calligraphy Park" Landmark building.
