During the duration of the fund, investors can consult the fund contract or consult the customer service staff of the fund company for inquiry. At present, the duration of the fund is very long, so investors don't have to worry too much about the expiration of the fund, and investors can make inquiries as needed.

Duration refers to the indefinite period from the effective date to the termination of the fund contract. Closed-end funds usually have a fixed duration, and the duration of closed-end funds in the market is 10 year or 15 year. The state stipulates at least five years. Upon maturity, the duration can be extended with the approval of the fund holders' meeting and the consent of the regulatory authorities. However, open-end funds have no fixed duration. If the fund operation is approved by the fund holders, it can continue to operate.
