Please Help Identify This.

Hello. First, my apologies if this is not the correct area for this question. please let me know which would be the correct section as I have a lot more items to question.
I recently purchased a collection and this was in it. In English it does say Chinese Post Office Express Letter Ten Cents and the reverse says in English "Is is particularly requested that the exact time of receipt be filled in".
The rest is in Chinese.

So, can anyone tell me what this is? the value if any? I know it is a China Express Letter but other than that I have no idea.
Thanks for any help.
Bob

This is from express letter stamp of Republic of China. From 1916 I belive. You have parts B and C. This would have as whole 4 parts and a tab. Later they were used only as receipts, not as stamps. I think that yours are from that period

And here is the whole thing, but slightly different version.

I don't know the value, and how does it influence the value that it has only 2 parts. However, my understanding is that as the result of normal use it gets separated in different pieces and is in normal condition for postally used one.

Thanks! This is awesome information. Now I can print out your replies and keep it with the stamp for identification.
Thanks again!

You are most welcome. If you have access to Yvert & Tellier catalogue of China, they might list it.
