"Shanghai Stock Exchange" refers to the use of exchanges to subscribe, purchase and redeem open-end funds, also known as "floor trading" of open-end funds. In this way, investors can buy and sell all the open-end funds listed on the SSE just like buying and selling stocks, which saves the tedious work of opening accounts and running around many times, and can query the information of open-end funds more conveniently and fully, making fund investment easy and efficient. Investors who want to buy and sell funds through "Shanghai Stock Connect" must first choose the brokerage business department with the qualification of "Shanghai Stock Connect", and investors can directly consult the account opening business department. If you already have a Shanghai securities account and handle designated transactions in the qualified brokerage business department, investors can subscribe, purchase and redeem directly on the floor.
