China Securities Co., Ltd. is a centralized registration and settlement institution under the Securities Industry Association of China, which is responsible for the registration and settlement of securities transactions and account management. Fund account refers to the account opened by investors for buying and selling funds. Unbound fund account means that an investor has opened a securities account (A-share account) in China, but has not opened a fund account with a fund company, so he cannot conduct fund transactions.

Binding fund accounts is the basic requirement for investors to conduct fund transactions. Investors need to choose a fund company first, then open a fund account in the fund company and transfer their own funds into the account. Investors can only buy and sell fund shares by binding fund accounts.

If the China settlement is not bound to a fund account, it may be that the investor has not chosen a fund company to invest, or has chosen a fund company but has not yet opened a fund account. To solve this problem, investors need to choose a reputable fund company, open a fund account in the company, and then bind with China Settlement to start fund trading.
