@ iTeach: Like herding cats - what do you want done about it?

Another issue, or maybe the same one: I realize the gokunming staff does not include a meteorologist, but the gokunming weather forecast, updated at 5pm, said 'Partly cloudy... 85% humidity...'

Ten minutes later a crashing thunderstorm came down on my apartment & lasted for about half an hour... Now it's sunny...

Science fails again... claim that sunset will be at 6:50 today, what are my chances?

About HPV & cancer & numbers: What are the odds in Vegas?

...as Herenow seems interested in the issue as well.

Would like to hear more about prices paid to artisans vs. profits for shopkeepers/marketers etc.

I think cloudtrapezer is generally right about registering weeks late, but I don't think anybody should take it as guaranteed - I remember a particular weirdness that happened to a friend, although it was over 10 years ago.

However, on Sunday I arrived in Kunming late, coming from abroad; law says I have to register within 24 hours; I went to the PSB 48 hours later, and because of National Day/week, the person who registers (foreigners, at least) wasn't on duty. The cop on duty there checked with somebody upstairs, then told me to come back early on Sep. 8. I plan to do so, but you can see that it's (often, I believe) somewhat loose.
Have never had the slightest trouble or aggro at my local PSB office, over many years and with various types of visa. Maybe once a year (actually it seems much less often) a cop does visit my flat, look at my passport and then leaves, no hassle.
