The two financing businesses refer to margin trading and securities lending transactions, which are divided into financing transactions and securities lending transactions. Financing transactions are when investors use funds or securities as pledges to borrow funds from securities dealers for securities trading, and repay the loan principal and interest within the agreed period; securities lending transactions are when investors use funds or securities as pledges to borrow funds from securities dealers. When securities are sold, within the agreed period, the same quantity and type of securities are purchased and returned to the securities dealer and the corresponding securities lending fees are paid. Generally speaking, the key to margin trading and securities lending transactions lies in the word "financing". Investors with "financing" must provide certain guarantees and pay certain fees, and return the borrowed funds or securities within the agreed period.
