Focusing on the Huajiaoqing tunnel as a background, the following were studied and analyzed: common architectural and decorative features of Bai residences, the pattern development of the tunnel portal,the landscape design principles and the present status of the tunnel portal. The landscape design overview of the Huajiaoqing tunnel portal is described, and recommendations are put forth in order to address regional cultural inheritance through structures like tunnels.
