The upper temple complex comprises the mountain gate, the Flying Rainbow Tower, the Amitabha Hall, the Great Hall, the Vairochana Hall, the Kwan-yin Hall, the Ksitigarbha Hall, as well as wing-rooms and corridors, among other features. The Mountain Gate, situated at the entrance, is flanked by two guardian warriors. Just beyond the gate stands the impressive Flying Rainbow Tower, constructed from colored glaze bricks. Originally built during the Eastern Han Dynasty (25-220) and later restored in the Ming Dynasty (1368-1644), this thirteen-story tower soars to a height of 47.31 meters, featuring an octagonal plan. The tower is adorned with tri-colored glaze in yellow, green, and blue, creating a splendid and vibrant spectacle. Elaborate wooden square blocks and intricately carved designs of Buddha, Bodhisattvas, guardian warriors, flowers, birds, and animals adorn the eaves and pillars. Corridors encircle the first story, while the tower’s interior houses only the stairs leading to the tenth floor, showcasing remarkable architectural and artistic prowess.
