There is baggage storage near Gate A domestic arrivals at Changshui airport. They put your bag through a scanner and you need to register with your passport.

It costs 20 RMB for the first 24 hours then 10 rmb for each extra day.

good point about the passport number, I asked if they can update the number on my title and land use deeds, but if they do that they reset the clock on the timing of the sale,,and after 5 years since the previous sale your tax burden is very different,,so keep those old passports,,,

You should use your legal name ie what is on your passport. I did that on my apartments title deeds. It's not a problem. If you are putting money into buying the apartment then have your name on the title deeds. In cases where two people own an apartment you should have both names on the title deeds.

you need to go to the webpage of your local police (in your home country) order your criminal record,,if you have any crimes registered then I would stop the procedure at that time.

If you have a clean record then get the record legalized at your department of Foreign Affairs (not sure the departments name in the USA) then take this to the Chinese embassy to be legalized, you can then show the cops in Kunming you are a good citizen.

If you have a copy of your criminal record here then you might try to see if the Embassy will legalize it before asking the Chinese Dept of Foreign affairs to legalize it, but I have only done this overseas so not sure if it works in China. Otherwise order the record on line and get friends inthe States to do the rest of the work,

Apart from marriage, there is a way to apply for the Green Card if you are a Deputy GM or above level in an "approved" company in China for (I think 4 years).

My old GM got a green Card like that. The "Green Card" is actually a 5 year residence permit in your passport and a Chinese Style ID card that says Premanent Residence Permit (Yes it was spelled wrong,,maybe they have corrected that by now).

The only trick to getting this was that the company had to be in a special class of companies, ie High tech or Export company, with all the certificates.

When our ex GM went to get his PR there was one other westerner and about 60 Kunming dialect speaking middle aged people who had lived in Kunming for all their lives but had never been able to get Chinese citizenship as their parents were Chinese refugees from Vietnam.

If you are a foreigner who was born Chinese or have Chinese ancestry then there is another PR class for you to apply for. This is much easier to get.

Unless they change the rules for PR I doubt many non Chinese born people (or those not married to Chinese) will get it, its mainly a way for the Chinese government to allow non citizen Chinese stay in China.
