In the case that the borrower can't repay the loan, the guarantor will bear joint and several liability, that is, if the borrower can't repay the loan, he will find your guarantor!
Generally speaking, the guarantor is a teacher or civil servant with a stable income. The credit union will cut off your salary, that is, your salary will flow into the credit union every month to repay the loan, not to you. So this has a great impact on the work of the guarantor.
