A song from Chengdu revived a closed-down pub.

As soon as Su Fan transmigrated, he received news that Fang Cheng, his brother who grew up with him in the orphanage, was going out of business running a small tavern in Sichuan Province.
So Su Fan immediately threw a song, "Chengdu," at him.
As a result, not only did the tavern thrive, but the tourism GDP of the entire Sichuan province also surged.
While the iron was hot, "Sorrow" caused another sensation, and the tavern became a must-visit spot.
After two songs, major entertainment companies naturally took notice of him.
But some people have the audacity to demand the copyright of the work.
Su Fan immediately responded with a song called "Nie," without mentioning any names or showing any mercy.
Still not satisfied with his outburst, he decided to start his own entertainment company.
As his fame grew, people gradually began to notice his background.
The details of their background also began to surface.
PS: The protagonist of this book, Su Fan, is intelligent and not a naive newbie. His friends are supportive of each other and there are no oddballs who take advantage of others. You can read with peace of mind; I will never cause any trouble for you, my dear readers.
