Explanation:

1. The interest is too high: within two years, the interest of 30,000 yuan will reach 1 10,000 yuan, which means the annual interest rate is about 50%. This is far higher than the upper limit of loan interest rate stipulated by Chinese law, and far exceeds the interest rate provided by most legal financial institutions.

2. Possible illegal behavior: High interest rate may mean that the lender has illegal or high-risk operations, such as usury or other violations of relevant laws and regulations.

3. The borrower is more risky: If you accept this loan condition, the borrower will have to pay huge interest expenses, which will put great pressure on his economic situation and repayment ability.

Summary:

It is not normal to borrow for 30 thousand years at an annual interest rate of 50% and generate 10 thousand interest. Such interest level is much higher than the upper limit stipulated by law, which may involve illegal activities. Borrowers should be cautious and seek more reasonable and legal loan methods.

Extended data:

In China, the loan interest rate is strictly limited by laws and regulations, and different types of loans have different upper limits. For example, the annual interest rate ceiling for personal consumption loans is usually 24%. Some low-risk borrowing methods, such as bank loans, usually have lower interest rates. The borrower should choose a legal financial institution, understand and confirm that the loan interest rate is in compliance with the law.
