Refers to the business run by government departments to pay pension and medical expenses for active and retired employees who participate in social insurance. The relevant wages and other funds will be automatically transferred to the bank card or personal settlement account agreed by the depositor in advance, and wages will be paid on behalf of enterprises and institutions, and social welfare insurance benefits can also be paid on behalf of the Social Security Bureau.

Fund refers to a way of centralized management of a certain amount of funds. According to different risks and returns, funds are divided into money funds, bond funds and stock funds.

The fund mainly makes profits in the following two ways:

1, net value growth: buying a fund mainly means buying a basket of stocks, and the net value of the fund represents the profit and loss of stocks. The growth of net worth naturally brings the income of investment.

2. Dividend: According to the national laws and regulations and the provisions of the fund contract, the Foundation distributes the income regularly. Dividends received by investors are also an integral part of profits.

In 2022, the fund we said refers to the securities investment fund, mainly referring to Public Offering of Fund. To put it simply, Public Offering of Fund is a wealth management product that regular fund companies raise funds from all qualified investors through various public channels and then use them for securities investment. Generally speaking, you give money to professional fund companies and let them help you invest in stocks, bonds and other securities. Of course, fund companies will charge a certain management fee.

Open-end funds are not fixed in scale and are not listed and traded. Investors can generally purchase and redeem at any time through fund companies, banks, brokers, and third-party sales platforms such as Ant Wealth and Tian Tian Fund.

Because closed-end funds are traded by bidding in securities trading, the transaction price is affected by the relationship between market supply and demand, which does not necessarily reflect the fund's net asset value, that is, the transaction price of closed-end funds has a premium and discount phenomenon relative to its net asset value. The practice of foreign closed-end funds shows that the transaction price often has the price fluctuation law of first premium and then discount. Judging from the operation of closed-end funds in China, no matter how the fundamental situation changes, the transaction price trend of closed-end funds in China has never deviated from the price fluctuation law of first premium and then discount.

Open-end funds only have a net quotation every day, and the purchase and redemption are based on the net value of the day. After the stock market closes, fund companies will calculate the net value of the day, which will generally be announced on various platforms before 10 in the afternoon, and the scale of open-end funds will increase or decrease with the buying and selling of investors.
