Make a couplet for you, or continue a poem. It can be seen that "Songkou" is an anthropomorphic rhetorical method in poetry. "Song" is a human being, and a verb "knock" describes the artistic conception at that time: it turned out that the poet was playing Go, but it was not written in the poem, but described as "Song" knocking at the chessboard. This is a common rhetorical method in ancient poetry. For example, it rains on the porch window on summer nights. It obviously rained, and the raindrops hit the bamboo bushes and the porch windows, but the poem said, "Bamboo hits the rain", expressing the poet's truth that he heard the sound of falling rain hitting bamboo and knew that the rain was the same size.
