In harmony with the surrounding landscape and buildings. The reason why the Twin Mountains in Shanghai are only 48 meters high is to coordinate with the surrounding landscape and buildings and minimize the impact on the surrounding environment. Gemini Mountain is a part of Shanghai World Expo Cultural Park, surrounded by Expo venues and residential areas. Therefore, after discussion, the government decided that Gemini Mountain is 48 meters high. This can be in harmony with the surrounding landscape and buildings. Gemini Mountain is the first artificial natural mountain forest with a height of over 40 meters in China, and it is also the first artificial mountain forest built on soft soil foundation. In the construction process, innovative technologies and methods are adopted to meet the challenge of soft soil foundation and realize the stability and safety of the mountain.
