Hello, at present, the common channels for purchasing funds are official website, banks, securities companies and third-party purchasing channels. One of the common fund handling fees is to purchase through securities companies. Usually, there will be a so-called "1 preferential fund" in the APP launched by securities companies. This discount of 1 means that the appraisal/subscription fee is 1. However, to purchase funds through a securities company, it is necessary to open a capital account in the securities company (no need to open a stock account).
