They also mandate a master degree and low effort from the company, which can be negociated if really strong guy (bachelor with some effory, expert reputation with high effort).
Then they give a permanent residency after 7 years of taxes but no path to nationality so the only way to persist is to make children locally, another interesting point: you ll never be Chinese but your kids can, which makes also the immigration problem drama free.
I quite wish France tried that because we feel (might not be rational) we have so many issues with our immigration.
