When I first arrived in china some years back I entered via a little used and distant land border in the north with my final destination being zhejiang province. Upon arrival at the PSB in zhejiang where I wished to get my z-visa changed to the full RP chaos broke out due to the fact that no one had ever heard of the place that was stamped in my passport. The initial opinion being that it must be fake with over a dozen officers coming to have a look and give their opinion. Finally after a couple of wasted hours they managed to make the necessary calls and found out that yes indeed the place in question was in China. They are ridiculous.
