The following are five problems Koreans have with bad credit.

1. Credit card overdraft: Due to the prevalence of credit card consumption culture in South Korea, some people may use credit cards for excessive consumption, resulting in overdraft and being unable to repay in time.

2. Loan default: Koreans will borrow money to buy houses, cars, etc. If they cannot repay the loan according to the agreed time, they will face default problems.

3. Tax arrears: The Korean government has tax standards for individuals and companies. If individuals or companies cannot pay taxes on time, they will face the problem of bad credit.

4. Apply for credit cards or loans multiple times: If a person applies for credit cards or loans multiple times, but is rejected too many times, it will also affect the personal credit record.

5. Violations: If a person commits illegal or irregularities, such as tax evasion, fraud, etc., he will also be included in the bad credit list.
