“ Let a wrong-doing repeat itself at least three times: the first may be an accident, the second a mistake, but the third is likely to be intentional. 让错误至少重复三次:第一次可能是意外，第二次可能是错误，但第三次很可能是故意的。 佚名
“ Great wisdom is generous; petty wisdom is contentious. Great speech is impassioned, small speech cantankerous. 大知闲闲，小知间间。大言炎炎，小言詹詹。 Zhuangzi 庄子
“ In this world, there is nothing softer or thinner than water. But to compel the hard and unyielding, it has no equal. That the weak overcomes the strong, that the hard gives way to the gentle -- this everyone knows. Yet no one asks accordingly. 天下莫柔弱于水，而攻坚强者莫之能胜，以其无以易之。弱之胜强，柔之胜刚；天下莫不知，莫能行。 Lao Tzu 老子
