You can buy and sell online banking, or you can make a fixed investment. The fixed investment amount is 300-500 yuan, and each company is different. You can also buy and sell funds over the counter, with a 30% discount on the online banking of the bank website and a 60% discount on the online banking of the fund company.
Some securities companies open accounts for free when they engage in activities, which is much better than the bank charging 25 (bank cards and fund cards). They buy the whole fund at a 60% discount, and CCB is still quite dark. Everbright Bank has many outlets and is free of annual fees.
The front-end and the back-end are the same, but it's just a matter of charging first, but the fund company wants you to keep the money for a long time, so the back-end will not charge after 4 years.
