I decided to buy a real estate index fund at that time, mainly because of two factors. The first is that real estate is the territory of China people. Although the overall price increase in the past 20 years has been quite high, there is still room. The second is the valuation of the real estate index, which is close to the bottom of history by the end of 2020. At that time, I felt that if I entered the market near the bottom, even if I continued to go down, the space would not be too big, that is, the risk was controllable.
