If you have already opened the fund account required by the open-end fund, you can buy it. At present, Hong Kong, Macao and Taiwan residents living in China can hold relevant certificates to open an open-end fund account in the sales department of GF Securities. If you are not a resident of Hong Kong, Macao and Taiwan living in China, you can consult the corresponding fund company to confirm whether you can open a fund account to purchase domestic open-end funds.
