Why are there so many second-hand houses in Changping Lijing Garden?

Lijing is an early development property, mainly based on the conceptual design of Hong Kong people; At that time, Hong Kong's economic environment was good, Changping's living index was low, and it was close to Hong Kong. Many Hong Kong people choose to buy a house in Changping for their holidays. However, in recent years, Hong Kong's economy has deteriorated and Changping's living index has risen again. Coupled with the change of house design concept, many people have sold their houses.
