After the King of Qi ascended the throne, Mr. Nan Guo lost his original job, and he couldn't do any other work. He had to live on the streets, helpless and suffered a lot, so he studied hard to play the flute. On this day, he begged all the way to the state of Qin, hoping to learn from Mr. Northland, the most famous blowing master at that time. Mr. Northland refused to accept such students at all, but Southland was not discouraged. He goes to Mr. Northland's house to help with his work every day and secretly watches Northland play the flute. Three years later, he finally moved to the north and happily accepted him as an apprentice.

Mr. Nanguo studies very hard. Every day, except for helping the Beiguo family, the rest of the time is spent practicing blowing. Beiguo was moved by his infatuation. Seeing that he was also smart, he taught him all the skills of blowing. Mr. Nanguo has suffered a lot before and knows that learning is very important, so he learns to play whenever he has time. In winter night, he was afraid of affecting the teacher's sleep, so he came to the snow to practice alone, and his hands were so cold that he couldn't feel it. At noon in summer, the teacher wants to take a nap, so he goes to the sun to practice, and his back is covered with skin. Through his efforts, three years later, Mr. Nanguo finally became the best student of Mr. Northland.

Mr. Nan Guo returned to China after finishing his studies and wanted to continue to go to the King of Qi, but he was driven away by the King of Qi, so he returned to his hometown and started a blowing school. At first, no one came to learn from him, because everyone had heard the story of him cramming for the last minute, but Mr. Nanguo was not discouraged at all. He didn't write and blow textbooks every day, but spent the rest of his time playing in the study room. No matter whether it was windy or rainy, his wonderful voice attracted many parents. A parent made up his mind to send his child to a teacher in the south to learn to play the flute. Teacher Nanguo was very happy and taught the student very seriously.

A year later, the student played the flute quite well. Teacher Nanguo signed him up for the national flute playing competition and won the first prize. The student's wonderful flute performance caused a sensation throughout the country, and everyone knew the name of his teacher, Mr. Nanguo. As a result, Mr. Nan Guo became a well-known blow master, and everyone who went to learn from him had to queue up to sign up.
