Poet of Tang Dynasty.
Dai Xulun, a poet of the Tang Dynasty, once followed his teacher Xiao Yingshi to a place called Baidian. He saw a white-feathered rooster standing on a short wall. Seeing this, Xiao Yingshi casually chanted: "The white chicken in the White Shop crows in the daytime." Then ask Dai Xulun to write the second line. This was a very rare pairing. Three characters for "white" were used in seven characters. Dai Xulun was stumped for a moment. At dusk, the teacher and the student came to Huang Village. Suddenly, a yellow dog broke out from a farmer's house and rushed towards them. Dai Xulun was inspired and ignored the threat of the dog and said to the teacher: "The students already have the second couplet! - Yellow dogs bark at dusk in Huangcun."
