Why is Jackie Chan's movie called Pink Zone?

The main scene of Pink Zone is in Los Angeles, which was once a reservation of North American Indians. People in ancient China used to call uncivilized nations "Fan", "Yi" and "Man". Because the skin color of North American Indians is slightly red, China people who immigrated to Los Angeles in the late Qing Dynasty and the early Republic of China called North American Indians "red fans", so there was such a problem.
