Shooting an action sequence is usually physically exhausting, but veteran choreographer Sun Mengfei has a special method to make the actors comfortable.

Recently during a promotional event of The Track Action, a 48-episode TV series which has been running on Beijing Satellite TV since Nov 25, Sun revealed that he used food-sealing plastic wraps to keep actors warm during water scenes.

Besides, the crew had heaters to dry the actors when they finished filming.
