What makes a Teabowl a Chawan 

You're free to do whatever you have the patience for. Seize life, my dude! We only have so many years in us.

김은수 yeah look it up people! It comes from the country right next to Japan.

The Japanese Chawan derives from Chinese tea bowls. The term Chawan is literally Chinese for tea bowl. The Japanese Chawan tends to be influenced by Buddhism and the Wabi Sabi aesthetic where beauty and appeal comes the appreciation of flaws and defects. Raku ware in particular is highly prized. Anyone can make a Chawan. You don't have to be Japanese. But to make a truly Japanese Chawan you have to accept the impermanence and imperfections of the world and more importantly the flaws within yourself. By stating that only the Japanese can produce Chawan you have set up Japanese as a gold standard of perfection which goes against the very nature of Buddhism and Wabi Sabi. The father of tea ceremony Sen Rikyo emphasized the simple and the rustic. The very first Chawans he ever used for his tea ceremony were taken from peasant homes; even a simple and humble second hand cereal bowl or ramekin will do if you wish perform a tea ceremony.

Why being so aggressive? He decomposed the kanjis, which are exactly meaning what he said.

Precisely why I went back to the Japanese referent in the presentation. (Which I do speak, by the way.)

Wow Morgan. Learn manners. Or just kindness.
