Kung fu delivery man destroys two security guards

In China, a food delivery man attacked two security guards. The scene shows the man throwing a series of quick, precise blows, using controlled fighting moves. The guards try to fight back, but are unable to contain the attack. One of them falls to the ground under the force of the blows, while the other is violently pushed back. The video does not show the origin of the conflict or its outcome, but the speed and efficiency of the delivery driver clearly took the agents by surprise.
