When the enemy advances, withdraw; when he stops, harass; when he tires, strike; when he retreats, pursue.
Mao ZedongWe should never pretend to know what we don't know, we should not feel ashamed to ask and learn from people below, and we should listen carefully to the views of the cadres at the lowest levels. Be a pupil before you become a teacher; learn from the cadres at the lower levels before you issue orders.
Mao Zedong
