The Humen Station is located in the geometric center of the Guangdong-Hong Kong-Macao Greater Bay Area. However, the current station is narrow and small, the surrounding traffic is chaotic, the urban space has not been effectively utilized, and the railway elevated seriously fragmented the urban space. To solve the current situation, under the principle of maintaining the operation of the original station, we added new waiting halls at the south and north part, and connected the city with a public platform which will "stitch" the city to improve the quality of space and land use efficiency.
