有这样一则寓言；理发师傅带了个徒弟，徒弟学艺三个月后正式上岗，他给第一位顾客理完发，顾客照照镜子说：“头发留得太长。”徒弟不语。师傅在一旁笑着解释：“头发长，使您显得含蓄，这叫深藏不露，很符合您的身份。”顾客听罢，高兴而去。徒弟给第二位顾客理完发，顾客照? There was a parable like this; the barber took an apprentice and the apprentice learned the job three months later. He gave it to the first customer. The customer looked in the mirror and said, “The hair is too long.” The apprentice doesn’t speak. . The master explained with a smile: “The long hair makes you seem subtle. This is called hidden, and it fits in with your identity.” The customer listened and was glad to go. Apprentice finished the second customer and the customer took care of it.
