On my recent trip I got some tea described by the herbalist as 'forever young green tea'. He said it was similar to LongJing. The leaves are flat with indentation marks. I made sure he wrote the characters which never look like typographic fonts. After some work, I came up with Si4Ji4 meaning 'four seasons' and traditional Chang2 character meaning 'forever/long/length' for the first three characters followed by the two characters Qing1 Cha2 for green tea. I get some hits with Google but lousy Internet connection prevent any substantial web page display. Does this tea ring a bell with anybody.

PS Sorr, I cant even post the characters.
