Fund raising period generally refers to the time from raising to establishment, that is, the issuance period of the fund. At this time, if the fund does not reach the scale of raising, the fund cannot be established, but if it can reach the scale, it will be established. After the establishment of the fund, it enters the trading period, also known as the fund opening period, that is, the behavior of raising funds to invest in the market specified in the prospectus.
