The Tiger Swallow Style (Hànzì: 虎燕拳, Pinyin: Hǔyànquán, On'yomi: Koenken) is a deadly form of kung-fu, which Lan Di is a very skilled master of. Lan Di's father, Sunming Zhao was also a master of the style. Also Master Baihu is a practitioner of the style.
The style is derived from Yanqingquan, a combination of Dahuyan and Xiaohuyan and has strong hand moves, which are as powerful as a fierce tiger. It is feared by the Emperors of the past and thus prohibited by the Emperor Yanqingquan.
