What did John give them at the end of flowers of war? What does that "lucky cat" mean?

John didn't know what kind of lucky cat it was, but he thought it looked like a runaway white cat, so he gave it to Mosquito, meaning to give her an amulet or something.

Personal feeling: a manifestation of Japanese hypocrisy.

When the Japanese went to listen to the students sing, the little mosquito's cat ran out, and the Japanese knew that there were "female students" who liked kittens.

As for the other things in the bag, it should be: candy and chocolate that girls of thirteen or fourteen like.

It is a kind of hypocrisy for the Japanese to send these things when they pick up female students.
