Credit loans are repaid with principal and interest. The interest seems very low, but it is actually very high, because you have already paid off part of the principal, but the interest is still the interest of your loan of 200,000 yuan. So when you take out a loan, you should know the interest you have to pay.
But if you borrow 200,000 yuan, invest it and make a profit of 30% to 40% every month, there is no need to pay more or less interest.
