Returning to Chinese nationality, how difficult is it for foreigners to get Chinese green cards?

Some people on the Internet joked about whether Bill Gates and Buffett are good enough, and whether they want to settle in China. The result is that they can't! Because under the current system, they do not have the Chinese work experience required by current regulations. This popular joke on the Internet is actually not a joke. China’s “green card”, which is the permanent residence permit for foreigners, is ridiculed as the most difficult “green card” in the world to obtain. Because less than 5,000 foreigners were obtained. Julian from France said that it is indeed difficult to get a "green card" in China. For example, you can apply for a green card as long as you have been married for a certain number of years. If you are qualified to apply, whether it will be approved or not is another matter.
