How to comply with legal rules? It’s even worse in other countries.
Speaking personally, I recently spent about a year living in Spain (helping out our Barcelona office) and I read everything I could on Spain visas before I went but I knew that I still didn’t know enough to do it on my own. So I hired a really good and really expensive Spain immigration lawyer and in about three hours she totally set me straight and I walked out of her office knowing exactly what to do and I did it and it worked. 90 percent of what I had read about Spain visas on the internet was true but ten percent that was either dead ass wrong or had changed recently changed or just did not apply to our specific situation. Had I gone with just what I had learned on the internet, I likely would have been booted out of Spain in 90 days. Despite all that I had learned by going through all of this, when it came time for another American lawyer in my firm to take my place in Spain, he too went to this same Spain immigration lawyer and he reported back to me the same result. She saved him huge amounts of time and huge amounts of problems.
And the whole point of this excerpt is that China is way worse.
