Very good discussion going on here this afternoon. I do believe that the China knows Japan comes from the same DNA as themselves and has enlightened Japan on this matter. There ancestors (one of the band of ETs up there) must have built something under the Great Wall that emits a signal. I believe the signal went into space only. The message was received and a signal sent back to earth is the key. Everyone received a message (or proof if you like) in there ceramic package and Japan received a different one than everyone else.

Hows that for thinking outside the box.
