The investment liquidation methods of such funds include contacting fund companies, contacting handling financial institutions, and not investing money for three consecutive months.

1. Contact fund companies: The most common way for closed-end funds to make fixed investment is to contact the invested fund companies by telephone, email and online platform to express their willingness to make fixed investment in closed-end funds.

2. Contact the handling financial institution: bring my ID card to the relevant institution that purchased the fund and terminate it with the help of the staff.

3. Don't save money for three consecutive months: If you don't save money in the fixed investment account for three consecutive months, the fund company will automatically cancel the fixed investment business of investors.
