Why was China flight yesterday?

Is this flight a coutesy flight which means hands across the sea with national emblem concerned with my HP written down the day before yesterday?

Optimistic? But intersting! Thank you ,China! I will surely think a lot about relation ship China and the U.S and Japan and a world and peace.

Again,China!!

WHAT DO YOU THINK IT ?US AIR FORCE. AGAINST THE SOUTH CHINA SEA? BUT CHINA WAS SMAILING.IT`S NOT SERIOUS I GUESS.

GO,USA!!
