If you work in a private hospital, will you have the opportunity to go to a public hospital in the future?

If you work in a private hospital, you will have the opportunity to enter a public hospital in the future.

However, since I have already gone to work, it depends on the salary in private hospitals, which is higher than the position in public hospitals I intend to take an examination of, because public hospitals have also become state-owned enterprises, and the salary may not be higher than that given by private hospitals. Now both public hospitals and private hospitals buy social security, but the welfare benefits may not be high. After a thorough investigation, I thought it would be better to take the exam in a public hospital, so I made up my mind to gamble, even if I lost.
