Why is there an empty plan for Beijing in Sun AD?

Sun AD has an empty building, which is caused by high price and poor location. Sun North Zone was built in 2005 by Beijing Xinyuan Zhucheng Real Estate Development Co., Ltd. The total number of buildings is 13, and the number of houses is 1 897. The residential property company is Beijing Yanjingdu Property Management Co., Ltd. The price composition of Sun AD vacant building is unreasonable, the price is too high, the real estate marketing methods are backward, the publicity is not enough, and the property management is lagging behind, which affects the real estate sales.
