I went to a China Post branch in Haidian and this post office said they don't handle international postage. Which post offices in Beijing do handle international postage?

I am confused, i did some research and some said that epacket is only exclusive to Ebay Seller. is it true??
if not, can i go to any post office to send this postage?
I live in Hong kong, if i go to Shen zhen will i able to make this postage??

Thanks
Ryuichi

Hi, I REALLY NEED YOUR HELP PLEASE. HERE FRENCH POST OFFICE
TELL ME WE DON T KNOW ABOUT CHINA POST OFFICE.
Could you please, tell me in which post office is my parcel?.
i checked again the number there is CC in front number
French tracking number is : CC970862996FR or EB970862996FR.
I gave you before Chinese tracking number (11515297086299) that someone from France post office give me as your reference but you said me it is not a Chinese tracking number.
I think here they don't know your reference number or made a mistake in giving me. Then I called again to check and obtain your Chinese tracking number and they answer me WE DON T KNOW THEIR NEW REFERENCE NUMBER CHINA TRACKING NUMBER.
I'm desperate, how to found my parcel please?.
Then my boyfriend Mr Zhang (the person for which the parcel is) will know where to pick-up the package. Please answer to this email at: [email protected] And please : [email protected] MANY THANKS FOR YOUR HELP AND PATIENCE. Best regards. Valerie
