Zhejiang Xinyi house has always been guaranteed to be a real house. Is it credible?

According to news reports, Hangzhou Housing Authority has been pushing the "five realities" housing system recently: real existence, real property rights, real entrustment, real price and real pictures. As long as the housing released to the outside world must meet the conditions, the old intermediary such as Xinyi Housing must be trustworthy! Many of my friends bought relatively good houses through Zhejiang Xinyi House.
