Who Else Has Seen The 'Hidden Strike'?

One of the things I'm glad about technology advancement is the ability to see a movie of less than 2hours within 13 or more hours. That was exactly my experience with having to attend to my baby to, attending to other house chores.

Despite the many disjointed sessions, I still followed the story line a bit. This is because one of the star Actors, Jackie Chan, is one of my favourite Actors because of the comic relief attached to his movies, as well as he showcasing the practice sessions while making the movie.

The story line was okay, although I still don't know how a refinery was situated in a desert. My confusion came from the actions of this man in the image below.

While marking the bus professor Cheng was inside.

The two scenes I saw him was while he was marking the vehicle and when the guys entered the bus, as seen below.

Apart from those scenes, I can't remember any other roles he played or how it ended up with him, having served as mole for the attacks. Have you seen the movie and what's your thoughts.
