Kunlun has a strict code of conduct laid down for its members, who are forbidden from associating with people from unorthodox schools or else they will be expelled.
Although Kunlun is considered to be a Taoist school just like Quanzhen and Wudang, it accepts students of both genders, and members are allowed to marry and start families, and are not bound by any regulation to maintain vegetarian diets.
One notable trait of the school is that it has a strong desire to become one of the superpowers in the wulin, and some members are especially extreme in their plans towards achieving this goal.
In Jin Yong's The Heaven Sword and Dragon Saber, He Zudao and He Taichong are depicted as ruthless and ambitious individuals who wish to dominate the wulin.
[1] He Taichong, in particular, is depicted as a morally bankrupt villain who resorts to unscrupulous means in his attempt to seize hold of the Dragon Slaying Saber and use it against his rivals.
