If you can't make it in time, I recommend the Palace Museum's Green: Longquan Celadon of the Ming dynasty. The collection is breathtaking. These antique objects have such grace, their colors are so vivid and natural. It is even possible to touch a (broken) piece of celadon. Their texture is soft despite being thick. Amazing. (At least click on the link for a virtual tour. Until October 15, 2009)
On the way out of the museum, I picked this book: Empty Vessels, Replenished Minds: The Culture, Practice and Art of Tea.
Perfect: paintings, books and imperial tea artefacts all related to Chinese tea!
