Introduction to the wall collection building: In order to allow more people to appreciate the exquisiteness of the wall collection in the Bojia Temple, this Tiangong Pavilion, known as the "Original in the Overseas", has been enlarged dozens of times in proportion. It is replicated as an outdoor building in Yansi Square.
