I was recently given some tea that I think I've figured out to be Tie
Guanyin. It appears to have been made in the PRC, but the packaging is
in Japanese. I figured out most of this from the little sticker that
comes on the bottom of the metal cannister and which has the name of
the tea, the amount, the company, and the origin (in kanji/Chinese).
The sticker also has one other feature--in Chinese it says "year,
month, day" and the corresponding information is something to the
effect of 55, 5, -6. This cannister does not look anywhere near 50
years old. I haven't looked at the tea because it is in a sealed
tinfoil bag and have too much other tea to get through before I open
this. Anyone have any idea why the year would be written as "55"?
