The sudden price reduction in Ocean Wuli Spring and Autumn Period is due to a large number of restricted competition rooms entering the market. In today's Beijing property market, a large number of competitive houses have entered the market, and a small number of pure commercial houses have also entered the market. In terms of second-hand housing, only 72,600 sets were sold in Beijing in the first half of this year, which is the lowest value of second-hand housing turnover in the same period in five years. Property buyers have a strong wait-and-see mood, and developers are under great pressure, and some special rooms will be launched to attract property buyers.
