Ruilian Pavilion is located on the west side of the first courtyard of Ancestral Temple of the Three Sus and faces east. It was rebuilt in the fourth year during the reign of Emperor Kangxi in the Qing Dynasty (1665). To expand the west Ruilian pond, governor Zhao Huiya built the Watching Lotus Pavilion on the pond, which is now Ruilian Pavilion. The pavilion has 8 corners and 12 pillars, with a length of 2.65 meters, a height of 7.9 meters, and a building area of 62.7 square meters. The pavilion is surrounded by armchairs, with a single-eave roof. The top of the pavilion is a vase-shaped ornament, with animal figures on all 8 ridges, and the roof is covered with semi-cylinder tiles. The door of the pavilion opens to the east, with a small bridge connecting it to the shore, and the pavilion is surrounded by armchairs. The pavilion is decorated with a plaque reading 'Rui Lian Chong Xian (Lucky Lotus Reappears)', which was written by Neng Tai, the governor of Sichuan in the forty-sixth year during the reign of Emperor Kangxi (1707). Su Xun once planted lotuses in the pond.
