Although Li Shutong is good at lyrics and songs, the biographer Mr. Chen Xing verified that this song is not a poet's lyrics, but a tune of an American pop song, and the lyrics also refer to a Japanese song-some critics believe that the lines condense the artistic conception of the fourth part of The West Chamber. However, these two songs may have been lost in the ocean of history in the United States and Japan, but this song, which borrows chickens to lay eggs, has gained a long and even eternal life in China. "Outside the pavilion, by the ancient road, the grass is green. The evening breeze blows the flute, and the sunset is outside the mountain. " It is hard not to become a famous song of China, especially in the 20th century, when the old and the new changed and Taoism was destroyed, with such simple and profound but sad and soft words and soothing melodies with China characteristics. This song became the new Three Stories of Yangguan, and people in China in the 20th century used this song to "send away" too many things.
