Daytime UFO Captured Shooting Orbs---2014 China

A video taken in the daytime of a UFO has appeared on youtube. In this video, we see a white orb moving through the sky. The orb then stops and shoots out other orb that proceed to gracefully fly through the sky as if putting on a show for the onlookers on the ground. Are these orbs some type of personal ship for extraterrestrials or are they some kind of intelligently controlled device similar to a drone?
