Why didn't Jinhua Town in Xiaoshan District be demolished?

It's hard to plan after it's demolished. According to the announcement of Xiaoshan District, most villages in Evolutionary Town of Xiaoshan District are located in the valley, and the terrain is very steep. Considering that it is difficult to plan the project after the demolition, the demolition plan was cancelled. Xiaoshan District, a municipal district of Hangzhou, Zhejiang Province, is located in the north of Zhejiang Province, the south bank of Hangzhou Bay, the south bank of Qiantang River and the south wing of the Yangtze River Delta, and is the most active county economy in China.
