Pythagoras & Zero - in Chinese!

I brought in my mail today and discovered, to my delight, copies of the Chinese translations of my books, What's Your Angle, Pythagoras? and A Place for Zero!  I'm usually informed about the sales of foreign rights, but I'm always quite surprised when translated copies arrive in the mail - a really fun surprise!  I love seeing the foreign publishers' different approaches to cover design - quite different from the American versions!  There's barely a word of English to be found in these books, but I see a url on the back cover for Foreign Language Teaching and Resource Press, so I'm going to guess that's the Chinese publisher...
