Now that it was the era of peace, where society got along harmoniously, the interaction between martial arts practitioners was focused more on the technical side of things, so while it was inevitable for them to exchange punches and kicks, everybody would absolutely refrain from using some of the more overly vicious moves against one another. Take that move Gu Fei had just used; it was indubitably a forbidden move. If this move were to be executed in reality, the recipient's family line would end right there and then. In the event that the recipient was from a family that only imparted their martial arts to people related by blood, and the person had yet to have offspring, then this move of Gu Fei would literally sever a kung fu inheritance. The consequences would, thus, be disastrous.
