The Japanese have maintained their human standards very well, as have so the Chinese. I would guess that there would not be as much a problem in tracing blood lines in these country's as it would be here in America.It still amazes me that a person can devote his life to carving something that is a work of art, and when the carving reaches American hands, at a bargain, it is set on a shelf till dust gathers on it and then sold for nearly nothing at a yard sale. We are trying to cram too much into this short life,too fast, in so much of a way that we are bypassing, what life is all about.
