First of all, the credit line is the highest available credit line given by banks or other financial institutions according to personal credit situation and repayment ability. Simply put, it is the available credit line that is open to consumers after comprehensive consideration of credit scores and credit records. Credit limits are usually related to credit cards. A person's credit limit can vary according to personal circumstances, but it usually depends on factors such as consumer's credit history, income, stability and borrowing history.

Secondly, the cash withdrawal amount is the highest cash amount that a credit card holder can withdraw from his own credit limit. The withdrawal limit is usually linked to the credit limit, but it is usually lower than the credit limit. This is because the current practice is generally regarded as a high-risk behavior, because withdrawing cash may lead to people's debt situation becoming more serious. Therefore, banks usually limit the amount of cash withdrawal to help customers better manage their debt levels.

Finally, it is very important for credit card holders to understand the meaning of credit limit and cash withdrawal limit. This helps them to better control their debts and expenses. If the cardholder can reasonably plan his credit limit and cash withdrawal limit and repay in time, he can easily pay for shopping, travel and other expenses with his credit card. However, if the cardholder abuses the credit card and overdraws the credit limit or even exceeds the withdrawal limit, it may lower the credit score and damage his credit record. It should be emphasized that maintaining the habit of strict consumption and careful calculation is the key to maintaining a good credit limit and cash withdrawal limit.
