Louis Koo Tin Lok and Miriam Yeung Chin Wa, Vic Chou Yu Man recently worked on DON'T GO BREAKING MY HEART 2 (DAN SUN NAM NUI 2) in Guangzhou.
Louis worked on a building wall climbing scene and attracted many onlookers who secretly took photos and posted them online.
He was climbing outside the window and had a painful look on his face, reports TVB News World.
Employees on the other side of the window were very happy, kept taking photos and said, "Koo Tin Lok is shooting outside the company's window. The entire company is boiling, in the morning no one could work."
