Which law from which book? To quote from TFA

> The immigration officers explained to me that a new law that had come into effect in recent months meant I was unable to exercise the longer transit visa. My previous visits were not subject to that, I was told. The officials denied my request for details about this new law.

Most of the Chinese "law" are not lawfully legislated and are selectively enforced TBH.

Looks like some kind of special 规定 or 通知 targeted directly towards OP's visa.

The law, that as the top comment to the article points out, is on the back of the immigration card in English that you fill out when you enter.

I assume you're referring to this (http://www.joutrip.com/easyworks/data/gallery/china-departur...)? I see no mention of having to inform the police (or whoever you're supposed to inform) if you decide to spend a night at AirBNB..

It's #1.

Huh, I always read it as entry to the country, not entry to the apartment. Especially considering in #2 entry seem to refer to country. And entry is a really strange choice of word to use when referring to checking in to an apartment.

He is selectively choosing to read what he wants in order to trash talk as illustrate by his emotionally charged comments.
