If you were married when you bought the property then you will have to get your wife's permission to sell it, same as the house in your wife's name, when you want to do this.

When I sold my apartment my wife needed to sign all the documents, her name was also on the title deeds so this made sense.

However when I sold my car park I also needed my wife's written permission to sell the car park, even though she was not on the title deeds. Chinese law says that property bought by a married couple is jointly owned, so both parties need to agree to the sale.

The name on the title deed is copied from your passport.

As long as your official Z visa invitation letter says that the visa is to be processed in HK then you are good to go.

There is a nice yoga place near the old pumping station musuem inside Greenlake park. It's easy to find, sorry no link.

Looking at the regulations posted by HFCAMPO you see that foreigners need to register when they arrive in a new place in China or their old place after leaving and re-entering China.

But, I think the potential problem for the PSB (and us) is that the local PSB are responsible for checking on the status of the foreigners in their areas of responsibility. If they don't know you are gone then it may be "embarrassing" for them if you then re-appear from overseas or out of Kunming and they have to enter you on their system while it shows you never left.

In more strictly managed PSB system ie in Tianjin it would explain why they want you to let them know you have left their area so they can remove you from the system. Sooner or later Kunming PSB will ask for this too.

Last week the PSB from the Greenlake station called me to ask if I was still living in my old address or had left, I was a bit suprised because I have already moved a year ago and had registered my new address, all at the same PSB office, when I told her that she said, O that complex is done by a different collegue....and she hang up.

It's important to register with the police and keep it updated. Sooner or later police in different departments and even same offices will start talking to each other.
