Need Help With Chinese Stamps, Please.

OK! I c it. Thanks for the info Rod.

Zhang, as Rod said you are a Chinese expert to us, and it is a pleasure to have you here. Thanks very much for your help.

Nigelc, thanks for the extra info.
Mine is the more common 3mm.

I think I'm still a bit confused, but not as much as I was.

Zhang is that correct, it would make it one of the most valuable stamps I have.

Thanks Steve, I only can speak and read Chinese language, that is more convenient relatively than most Westerners to ID China stamps, about the philatelic knowledge of China, I am a newbie, lack experience, I am not be saying modest word. I have met a lot of Westerners who grasping the wide philatelic knowledge of China on SCF, such as Tom, Writehorse(Mike), Khj(Kim), Rod, Tony and Nigelc, and I know there are more Western Chinese stamps experts in the Western stamp world, and I am sure there will be more Chinese real experts come here and sharing with us.
