Sima Qian mentioned in "Historical Records" that Qu Yuan met a fisherman by the Miluo River. The fisherman sang, "The water in the Canglang is clear, and I can wash my tassel. The water in the Canglang is turbid, and I can wash my feet." In the confusion of time and space, this shallow singing caused not only the sigh of the fisherman, but also the deep thinking of Sima Qian not far away. . . . When Sima Qian met Qu Yuan, the gentleman he described as "whose writing is simple, his words are subtle, his ambition is pure, and his conduct is honest." What kind of sparks would be sparked?
