Tea set gift for Chinese boss

I have a Chinese boss who is around 50 years old, he is from Shanghai and went to Fudan university. He left China around 1992. He's been an amazing mentor to me and I want to get him a nice gift. He likes tea and I don't have the first clue about what is good! I want the set to be nice and possibly have some meaning to his area of upbringing/culture.

Which searching Ebay I found [this](http://www.ebay.com/itm/VINTAGE-HTF-8-pc-Longquan-Porcelain-Celadon-Tea-Set-Wood-Case-Pot-Pitcher-Cups-/132114607954) which looks nice to me but I don't know if it's meaningful, overpriced or even good!

It seem a lot of people are hip on this Gongfu Tea style. Is this good or are there better styles for his liking? I know he drinks loose leaf green tea. I've been to his place and he has a lot of I'm guessing porcelain/ceramic style tea glasses, the thin small white ones with decorative finish and a handle.

Can someone help me find a nice set that will be sentimental but also high quality?
