Yu Entai, a graduate student of Shanghai Theatre Academy, is very familiar with the screenwriter Caishen Ning. When filming this play, the writer recommended this scholar with good English to the director. Shang Dao told Yu Entai that he would play a knowledgeable scholar. In the following two months, Yu Entai recited the Book of Songs and The Analects of Confucius, claiming that he had experienced the charm of ancient China culture. Two months later, he wrote a paper about the origin of The Book of Songs. Shortly thereafter, as a screenwriter, he tried his best to recite poems impassioned, which excited everyone present. At the shooting scene, he was blindsided-in the script, whenever the scholar is ready to talk nonsense, people in the play will shout, "Shut up!" " From beginning to end, the scholar didn't say a complete sentence.
