老子毫无动静的坐着，好像一段呆木头。
“先生，孔丘又来了!”他的学生庚桑楚，不耐烦似的走进来，轻轻的说。
“请……”
“先生，您好吗?”孔子极恭敬的行着礼，一面说。
“我总是这样子，”老子答道。“您怎么样?所有这里的藏书，都看过了罢?”
“都看过了。不过……”孔子很有些焦躁模样，这是他从来所没有的。“我研究 《诗》，《书》，《礼》，《乐》，《易》，《春秋》六经，自以为很长久了，够熟透了。去拜见了七十二位主子，谁也不采用。人可真是难得说明白呵。还是 ‘道’ 的难以说明白呢?”
Lao Tzu sat motionless, like a piece of dead wood.
"Sir, Confucius is here again!" Geng Sangchu, his student, walked in impatiently and said softly.
"Please……"
"Sir, how are you?" Confucius said with a very respectful salute.
"I'm always like this," Lao Tzu replied. "How are you? Have you read all the books here?"
"I've seen it all. But..." Confucius looked anxious, something he had never been seen before. "I have studied the "Poetry", "Book", "Ritual", "Music", "Yi", "Spring and Autumn" six classics, and I think it is very long and familiar enough. I went to see the seventy-two masters, who I don't use it either. People are really not good at explaining, or is it just difficult to explain the 'Tao'?"
