王国维在《人间词话》里谈治学经验,他说:“古今之成大事业、大学问者,必经过三种之境界:‘昨夜西风凋碧树。独上高楼,望尽天涯路。’此第一境也。‘衣带渐宽终不悔,为伊消得人憔悴。’此第二境也。‘众里寻他千百度,蓦然回首,那人却在,灯火阑珊。’此第三境也。”治学有三境,? Wang Guowei talks about his academic experience in the book “Human Words,” and he said: “Ancient and modern careers and university inquiries must go through three realms: ’Last night, the West Wind littered with trees. Take the tall buildings alone and look to the end of the world.’ This is also the first situation. ’The belt is gradually widened and does not regret it. It is a ridiculous thing for the Iraqi people.’ This second situation is also.’ The crowd searched for thousands of Baidu. When he looked back, he was there, and the lights dimmed.’ There are also three borders."
