In China, if you want everything to go smoothly, you must remember one thing: to know that you don't know is wisdom, and to not know that you don't know is ignorance. Those who fall into calamity do so because they follow the words of sages. In this soil, you may understand everything, but you must not express your understanding; you may be clear about everything, but you must not be too clear and must speak in a way that no one can understand. You must be you, yet you cannot be you. You need to be both clever and confused.
