The original salary you quoted is only a reference for your new job salary. The salary you apply for depends on your performance in the interview and the salary range of the company for this position. How much you quote has little effect on how much you can get in the future. No one will doubt the normal market price range of your salary and position. Only when the level you showed in the interview is seriously inconsistent with your salary standard will someone doubt it.
Conclusion: If you think that the salary given to you by the original unit is not in line with your contribution and ability, just report the salary you think you should get, and there will be no problem.
