Not sure, it's a bit confusing with all these centers.
If you want to get more confused you can read page 17 in the 10-K, "Marketing & Trading Division" and "Project Development Division".
I get a feeling that they sometimes call the a Trading Center in Guangzhou for Wholesale Center 2 and sometimes a Wholesale Center in Shanghai the same name.
But the Trading Center should be a separate building in Guangzhou, but I thought that they already owned that one 100%.
