What is the origin and allusion of "Feng Qiu Yellow"?

According to legend, "Phoenix Seeking Phoenix" is a lyric sung by Sima Xiangru when he plays the piano. According to legend, Sima Xiangru and Zhuo Wenjun, one is a talented person who is regarded as a distinguished guest by the county magistrate of Lin Qiong, and the other is a beautiful woman who is waiting to be married. Their story began when Sima Xiangru visited Zhuo's family and played the famous song "Phoenix Begging for Phoenix" in Zhuo's lobby: "Feng Feng went back to his hometown and traveled all over the world to beg for phoenix. There are beautiful women in the boudoir, and the people in the room poison my intestines. Why did she make a mistake? " This kind of words, which are equally straightforward, bold and warm today, naturally made Zhuo Wenjun, who was listening behind the scenes, feel sincerely excited. After meeting Sima Xiangru, they fell in love at first sight and agreed to elope.
