If you want to buy it, Bank of China, China Merchants Bank and Bank of Communications all have agents. Just go directly to the counters of these banks. You just need to tell the bank counter how much you want to buy, and the bank will make a transaction memorandum, agreement and so on for you to sign and confirm. After signing, the purchase is complete.

You can also go to E Fund's company website to buy it. E Fund supports ABC, GDB, Xingye and CCB cards in online transactions. As long as the online payment function of the bank card is enabled, you can apply online.
