After years of spring and autumn, Hualin Temple had only the main hall, and later it added the mountain gate, the left and right halls and the porch. The main hall is a frame with single eaves and nine ridges, with a height of 15.5 meters and an area of 574 square meters. There are 18 wooden columns in the main hall, all of which are supported by a bucket arch, without a nail. Its construction method is unique among the wooden buildings in China in the Tang and Song Dynasties, which has a great influence on the "Buddha-style" and "Tencel-style" architectural styles in the Japanese Kamakura period (the end of 12). Although Fuzhou is rainy and humid, termites are rampant, and wooden buildings are difficult to survive, the main components of Hualin Temple still preserve the original objects more than 900 years ago. It is the oldest wooden temple in the south of the Yangtze River in China, and it is a precious material for studying ancient architecture in China. 1983 is listed as the second batch of key cultural relics protection units in China.
Although the main hall of Hualin Temple was rebuilt many times in the Ming and Qing Dynasties, and the lower eaves of the surrounding cloisters were added, its main components have remained the same for thousands of years, and it is the oldest wooden building in the south of the Yangtze River in China.
