I have order items from China and they give me and tracking number but no website.
My tracking number is like
RR###########CN.
So I find where I can check it for 2 days and give up.
One week later I try to do again and found website.
That is: http://intmail.183.com.cn/item/itemStatusQuery.do?action=Enter base on http://intmail.183.com.cn
I my item was in database.
I think is you got and tracking number like RR CN and can not find it in that website.
You should wait maybe for 3 days and check it again.
Don't be worry!!
