You have to pay liquidated damages for this, but the calculation formula is wrong. According to China's "Labor Contract Law", employers cannot claim liquidated damages from workers at will. According to the provisions of Article 22 of the Labor Contract Law of People's Republic of China (PRC), if an employer provides special training fees for workers and conducts professional and technical training, it may conclude an agreement with the workers to stipulate the service period.

If the laborer violates the service period agreement, he shall pay liquidated damages to the employer in accordance with the agreement. The amount of liquidated damages shall not exceed the training expenses provided by the employer. The liquidated damages that the employer requires the laborer to pay shall not exceed the training expenses that should be shared for the unfinished part of the service period.

If the employer and the employee agree on the service period, it will not affect the employee's improvement of labor remuneration in accordance with the normal wage adjustment mechanism during the service period.

To sum up, you can pay the company's training expenses at most, and the compensation amount of your company = the total amount of training expenses * means that the labor contract expires, which is illegal and therefore invalid for you.
