Baoyue Building is located at the southwest bank of Mochou Lake. It was built in 1960 and completed in 1983. Some of its architectural components were removed from Erlang temple, so it was once called "Erlang Temple". Baoyue Building is a two-floor archaistic architecture in composite structure, which is composed of one pavilion, one platforms and two angle pavilions. The stylobate of building is relatively high with many slabstones on the walls of stylobate. On the slabstones, it is engraved with character stories in "Water Margin" and "Romance of the Three Kingdoms", and with facing-up lotus petals, which are fine and vivid. A pair of stone lions in front of the building were moved here from the east gate of Nanjing Municipal Government in 1966. At the north side of Baoyue Building, there is a platform above the water, which is used for tourists to take a rest. The grand stage at the south side is the main arena for holding artistic performances in the scenic spot. The second floor is a good place to appreciate "the mists and ripples of Mochou Lake". Here, taking a rest to have some tea, overlooking Mid-Lake Pavilion and appreciating lotuses in water are so refreshing.
