Life In 19x19

Thank you for your reply.
Unfortunately, I also don't know where I can find the answer book.
What is the name of the Chinese version and where could I find it?

I'm looking for the same book: "Speed Baduk for Beginners, Vol 1, 2, 3 & Answer Book".
I could find no place in Europe that still sells this book.
The website http://pentanglepuzzles.co.uk proposed in an earlier post seems to be down now.
Can anyone help?
Thanks
