It's usual to declare where you are staying, it isn't usual to have to register with the local authorities in every place you do. I do accept it, countries have different rules and cultures. Foreigners do end up breaking such local rules when going abroad, including the Chinese. But doing so shouldn't result in being banished from the country. Imagine driving into Austria without a toll sticker and no longer being able to get a Schengen visa. Of course we don't know the full story. Hopefully this is more about the authors situation than something that will become commonplace.

It may be annoying or inconvenient, but China is not the only country a requirement to register with the local authorities. The fact that it applies to all types of visas may throw some travelers off. Still, it is their responsibility to make sure (preferably before arrival) that the requirements for entry are met.

When you break the rules (intentionally or not), you're taking a risk. Some people get off unnoticed whereas others learn the hard way. Ask people familiar with the country and its laws before arrival and plan your trip properly.
