Is it possible for China to accept large-scale Japanese migration?

I'm afraid it is impossible at present. At present, China is under great employment pressure and will not accept immigrants from any country on a large scale. It is ok to accept a small number of Japanese high-level talents. Not as good as Japan's 25 people won the Nobel Prize. Mobile phones all over the world rely on Japanese parts. For example, half of the parts of fruit mobile phones are made in Japan. What advanced design and manufacturing talents are needed?
