Why did Jincheng Bank send a message when it borrowed 360 yuan?

It is stated in the loan contract that 360 and Jincheng Bank jointly lend. 360 provides a platform and a small amount of money. Most of the money comes from Jincheng Bank. For example, if you borrowed 100 yuan, maybe 360 of them will be returned to 10 yuan, and the remaining 90 yuan will be returned by Jincheng Bank. So you just borrowed from Jincheng Bank through the 360 platform, and the natural message was sent to you by Jincheng Bank.
