I have been holding Southern Cash A and Southern CSI 3. The online transaction you mentioned should be the transaction on the direct selling website in southern fund, and the account opening you mentioned refers to the account opening in the sales organization (sales channel), which can be online direct selling, banks, brokers and so on. No matter which sales organization you bought southern fund from, you can check it on the Southern Direct Selling website. I personally bought the fund through the Southern Direct Selling website, and signed the ICBC online banking. It is very convenient to buy the fund after signing the contract.

I can trade directly through wap now. At present, I have released the trading software for iphone, but I don't have the trading software for Android. I look forward to it. If you only buy southern fund, I suggest you go directly to the direct selling website. If you want to own multiple fund companies, you can use Tiantianying, and the rate seems to be 4% off.

personal opinions are for your reference.
