I work right next to Boeing Field and I have never seen that plane with those colors. Is that just a 747-400 ??
That is a China Airlines 747-400 that was delivered last year. It has the new Boeing livery developed for the 787.

China Airlines out of Taiwan, not PRC.
The bloom on the vertical stab is their signature emblem.
