My visa was wrong, and I could not take the plane yesterday: The Chinese Embassy made a mistake 2 weeks ago when we asked for it.
They said: "look at the date, you can go to China until beginning of February".
Of course, the visa was fine until that date, but it was for one entry only! And I already used that entry in November :-(
The airport staff tried to join both Embassy in Tokyo, and Dalian airport, but they could do nothing.
So I went back home, I got Boudicca back, and I am waiting for my wife to come back end of next week...
