Firework-snatching, known in China as Qianghuapao, is a traditional sport of many ethnic groups including the Zhuang, Miao and Dong. The traditional way of playing is to launch a firework into the air and young men compete to get it. The arena could be any places, even ponds, cliffs, and so it is called a "game of brave guys". But the game has been improved into a new style, similar to American football, spanning 40 minutes in two 20-minute halves, with a ten minute break. The firework has been replaced by safer rubber disc with a diameter of 15 cm.
