This is true in all walks of life, depending on ability and experience.
Take Guangzhou as an example:
If you have no experience, it will be about 3000 to 5000 if you join the company.
If you have more than 2 years of experience, you can reach about 8 thousand to 1 10 thousand
If the experience is in 1978, 20,000 is not a problem.
Of course, what I said is probably because companies vary from industry to industry!
