Anyone who offends China will be killed no matter how far the target is." That is the tagline for Wolf Warriors 2, the Chinese box office hit that is equal parts testosterone-fuelled machismo - think blazing guns, explosions, and tanks - and chest-thumping Chinese patriotism. It sees a soldier venturing into an African warzone and saving hundreds of lives from Western baddies. It's basically the plot of your typical Hollywood action movie, but this time it's a Chinese man upholding justice and keeping the world safe. Following in the footsteps of Jackie Chan and Jet Li, martial arts expert Wu Jing is among a new generation of Chinese action stars turned directors.
