Generally, they sign a three-year labor contract, with a three-month probation period. One month before the expiration of the labor contract, the company will decide whether to renew or not renew the contract based on the company's actual situation and the employee's performance in the past three years.

Then the company will issue a letter of intent to renew or a notice of non-renewal to the employee. If the employee agrees to renew, the company will handle the renewal procedures.
