In fact, there is only one advantage of the building, that is, central heating, but there are many disadvantages: the annual heating fee and other expenses will cost your salary in February and March. Ten years later, the aging property will be an old building, and whether it can be warmed up at that time is a problem. Once an earthquake happens, it is difficult for three generations to live in one building. After 50 years of demolition, you have nothing. By the age of 70 or 80, you will be homeless, with dirty air, poor lighting and unsafe property. Because of the temperature difference between indoor and outdoor heating, children often catch a cold and have poor immunity. The building is boring, not as bright as the bungalow. The advantage of the bungalow is the disadvantage of the building. Buying a newly designed four-story bungalow can solve the housing problem of three generations. People of insight should act quickly before the price of bungalows rises sharply and stop driving up the property prices in Shenzhen.
