Historical source

The two brothers each used a hundred steel shields, which were both offensive and defensive, and the force of joint efforts was greatly increased. The You brothers are warm and generous, and everyone in the Jianghu used to make friends. They are responsive, and although their martial arts are not superb, Juxianzhuang enjoys great prestige in the Wulin. In the battle of Juxianzhuang, the You brothers broke their shields and committed suicide according to Master's command that "the shield is in the hands of people, and the shield is dead".
