In these largely fictionalized stories, he survived the battle against the Liao dynasty army that killed his father, and left to become a Buddhist monk.
He is also known as Yang Wulang (楊五郎) which means "5th son," and is a nickname rather than an official given name.
During the battle of Mount Twin Wolves, General Yang Ye's army was surrounded by enemies.
Having lost contact with his family in the battle, and knowing the Song army had lost the day, Yande left the battlefield and made his way to the Buddhist monastery at Mount Wutai (transliterated as Ng Toi in Cantonese).
The style he created became known as Fifth Brother Eight Trigram Pole, or Ng Lung Ba Gwa Gwan (五郎八卦棍).
