Xiao Shishan plays the flute, making the sound of husband and wife. Qin Mugong had a daughter who was good at blowing sheng, and her husband was a wife, so he taught her to be a teacher. After living for more than ten years, the phoenix stopped. The male is the Phoenix Terrace, and the couple stop on it. In a few years, Nong Yu went to Lapras, Shaw History by Phoenix. One day, when the sky was clear and the moon was bright, Nong Yu played Feng Huangming again. Music reverberates in the night sky, just like the sky in Yue Xian. Suddenly, she heard a loud flute, which seemed to float down from the eastern sky, obviously in harmony with her own music. After a while, I saw the Tianmen in the southeast wide open and pouring down the balcony. A beautiful young man landed opposite Cai Feng.

The boy said, "My name is Shaw History. I am a fairy, and I am here because I am destined for you. " The two of them-one person and one fairy, it should be said-played the piano on the Phoenix Terrace and hit it off. Shaw History is a fairy, and the flute travels thousands of miles. Played a song and attracted colorful clouds; After the second song, the red dragon dances; When the trilogy was finished, Phoenix chimed in. Manchu civil servants and ordinary people came to watch this once-in-a-thousand-year scene and were shrouded and shocked by the light of heaven and superb music. Qin Mugong happily married Nong Yu to Shaw History, and the young couple went to Huashan to live in seclusion. Under the training of Shaw History, Princess Nong Yu is getting closer to the standard of fairies. She can go on for months without eating or drinking, and the music she plays can reach heaven.

Finally, one day, God sent two flying machines-a red dragon and a gifted scholar Cai Feng. Nong Yu rode a phoenix and Shaw History rode a dragon. They all became immortals. This is the origin of the expression "son-in-law".
