Agree with tigertiger about the quality of chickens.

I'm staying at family in remote mountains at the moment, and the chickens are walking free outside the house during day, eating bugs and worms from the ground.

People seem to also feed them green food collected from the countryside (slashed to small pieces) or mashed corn.

For night the chickens come back to a small shelter.

Reverse osmosis is the technology commonly used, often together with filtration, to achieve high quality fresh water.

Outside drinking water production, reverse osmosis is often used to produce aquarium water clean enough to grow corals, or to desalinate fresh water from ocean water.

(Probably) not related to this, but during this holiday season has been the two first times during my 2 years in China that police have stopped me in street to ask my business.

First was when I was going back home, at the main entrance of the house. In addition to the regular security people, there was a policeman who wanted to chat me up.

The second time was going out of bus in a small city in Baoshan. That time there were several policemen outside, apparently checking every arriving bus and interviewing any suspicious people.

Both times I had a Chinese friend with me, so there wasn't much of a hassle.

The second time could have been tricky without Chinese speaking friend, because the policemen apparently spoke no English (not even "hello"), and my passport was in RP processing, so I only had the receipt for that.

A few weeks ago, there was a mini-soccer field set up at the newish Bin Jiang Jun Yuan apartment blocks. It had placards for soccer school, the name of which I cannot remember at the moment, but I googled it back then and it pointed to Hong Kong origin.

There were a couple of foreigners instructing children there in afternoons. Most of the kids were younger than 13 though.

The field was there for a couple of weeks. I'm guessing that it moved somewhere else after that.

I'm pretty sure they were recruiting parents to send their children to soccer classes, and probably not to HK. So there must be some operation going in Kunming. If only I remembered that school's name now.

Be advised that access to Google services are generally blocked by China. This includes those items you mostly need to prevent getting lost, the Map and the Translate.

Of course if you have other services to cover that, you'll be ok. Otherwise you'll need to be prepared with something to outsmart the Great Firewall.
