trying to decipher what exactly means the information written in the
chinese tins i have:

æ*‡å‡†ä»£å�·: WMB48-81(1) [babelfish: standard code number]
so i thought it was the code of the tea, the product, a code that make
it unique to find it better in a list...

but entering this letters and numbers [WMB48-81(1)] in google arrived
to this chinese web:
http://www.51st.cn/Webs/Skill/Show_Skill.asp?ID=4, in chinese

translating with babelfish [it's what i have at hand] i guess it's in
fact one of the standards used to regulate crops in relation with the
environmental damages they may cause. i understood that. so, in general
this web talks about tea gardens standards in Hubei province.

i thought it was at least curious to know. don't know if they are
strict environmental proctecting rules or what, in fact... but kept my
attention this was written in the tin as information to the comsumer.

another code in the tin:
�生��: (94)弟17-0021� [�生��: Hygienic card number]
could be a code for the firm that permits to handle foods? in spain we
have a thing called "registro sanitario" [health registry, or something
like that] like a registration number or license, one per firm. how is
it called in the us or other places?
