If it is online transfer, there are no restrictions on buying funds and securities. Reference: The new version of CCB Online Banking has restrictions on security passwords and transfers. If a static password is used, that is, the original setting, a single transfer cannot exceed 5,000 yuan, and the total amount of one day cannot exceed 10000 yuan; If you use a "scratch card", that is, you use a dynamic password setting, there is no limit on the amount, and online banking is safe. You can get a "scratch card" at the bank counter and bring your ID card. Or you can consult the local CCB outlets.
