Most of such "news" have no real data back them up.
I actually asked couple friends specialized in the area about it. What I learned is:
* Yes, they heard about there are some people from mainland buying houses in the area; but it's fairly rare
* Yes, there are people buying mansion in the area, but they dont seem to be people from China.
* And, there are lot of Chinese buyers; but they are just BORN in China (mainland); that they can tell from the names.
Last, the local market likes this kind of news (or rumors); it adds up the pressure for buyers. Free marketing tool, why not?
