Why are judges of Hong Kong Court of Final Appeal foreigners?

Legal analysis: Because the development of the Mainland started slowly in the past, and it experienced several instabilities caused by different reasons, on the one hand, it was worried because it didn't understand the truth, and on the other hand, it was used by people with a heart. Therefore, some people in Hong Kong, especially those with certain assets, chose to emigrate because they were afraid that things would be unfavorable to them after the reunification. Of course, at that time, Hong Kong immigrants were a little worried. Most of them earned their income through proper channels, so there was no need to worry too much. However, some people choose to return to Hong Kong to continue their development after obtaining local status because they can't adapt to life abroad or can't find suitable jobs.
