1. Insufficient parking space. The original building area of Heizhuo is about 26,352 ㎡, which leads to insufficient parking spaces on the ground, and many vehicles are parked in disorder, making it inconvenient to travel.
2. The environment is not good. The original building in Heizhuo occupies a small area, with a green area of only 30%, and the environment is obviously poor, so it is cheaper.
