Chihkan Tower is also called "Hongmaolou". It has been changed by Ming, Zheng, Qing, and even the Japanese dynasty for hundreds of years. It can be said that it is a witness to the historical changes in Tainan. Its architectural features range from Dutch-style castles to Chinese-style architecture. Today, it is not only an outdoor museum, but also a famous monument and spiritual symbol of Tainan. The Tanah Lot Temple on the south side of the Chihkan Building Complex and the Wenchang Pavilion on the north are two traditional Chinese buildings with red tiles. The attic that hangs the threshold of the "Red Mansion" is the Tanah Lot, which houses the cultural history of the Akasaka Building. Information, bypassing the back door of the Tanah Lot, there are two door-shaped holes like vases, which means "safe".
