Sun Simiao advocates "Twelve Less": think less, think less, do less, laugh less, worry less, be happy less, be angry less, be good less and be evil less.

In addition, we must guard against "more than twelve": if we think too much, we will be confused; If we are happy, we will forget our mistakes and become confused; If we laugh too much, we will get dirty; If we talk too much, we will be exhausted; If we want too much, we will be stubborn; If we worry too much, we will lose our minds; If we are angry, we will lose our pulse; If we are happy, we will be at a loss; If we are evil, we will become haggard and unhappy.
