They taught a lot of their kung fu to Dang and later introduced him to Wong Fei Hung to become an indoor disciple learning martial arts and Tit Da.
He learned Fifth Brother Eight Trigram Staff (Ng Long Pah Kua Guang) from Ling Wan Gai, the Generals Broadsword (Ji Fai Do) from Lam Sai Wing, the Green Dragon Knife (Ching Lung Yan Yuet Do) from Chan Din Biu, etc.
