The Sik Sik Yuen Wong Tai Sin Temple Nine-Dragon Wall building complex is also known as the Dao Enlightenment Hall. To tie-in with the development of the Yuen's affairs, in 2015, the Yuen planned to build a religious complex in the Nine-Dragon Wall garden for religious management, administration, and conference purposes. After more than two years of preparation, the building was finally completed in early 2018, and the opening ceremony of the Nine-Dragon Wall building complex or Dao Enlightenment Hall was held on February 9.

The Nine-Dragon Wall building complex is located next to the Wong Tai Sin Temple Main Altar, occupies an area of approximately 4,000 square feet, and has three floors. The calligraphy on the plaque of the Dao Enlightenment Hall was written by Professor Jao Tsung-i, the late master of Chinese studies. The complex has a guest room, multi-purpose meeting room, multi-purpose room dedicated to religious affairs, and an administrative office. The exterior wall is inlaid with a ceramic mural of a statue of Zhong Kui that is about eight meters high and three meters wide, giving it rich traditional Chinese characteristics. Beside it are three traditional green-brick murals that have the themes of Confucianism, Buddhism, and Taoism to highlight the Yuen’s belief that they share the same roots.
