The film "Jianghu of Music" tells the story of a group of post-80s students who graduated from the Conservatory of Music, their life and emotional experiences after leaving campus and their persistent pursuit of musical dreams. This is a story of music obsession. Because of my love of music, I have been insisting. For such persistence, they may have tasted it as they wish. In the rivers and lakes of music, they may gain or lose. This moment or the next happens in many corners.

Several good friends who graduated from the Conservatory of Music, Chen Hao, Zhou Mengmeng, Guli and Gangzi, entered the music world with their dreams. Guli runs his own band and performs everywhere. Chen Hao failed to send resumes everywhere, so he had to go to a bar to look for a job, and some people beat him to it. Chen Hao had no choice but to come to Tianqiao to sing and earn rent and living expenses.

Zhou Mengmeng's song was taken fancy to by a company called Taoyuan Culture, and he left Chen Hao with a note, and there was no news again. ...

Wang Jingjing, the singer of the Sea Bubble Bar, passes by the overpass every day, listens to Chen Hao play the last homemade guitar every day, puts down ten yuan and leaves. However, after Chen Hao didn't hear from MengMeng, he went to the sea bubble bar to drink beer every night, and he also found that singer Wang Jingjing was the girl who only wore a long skirt to listen to him play the guitar. They are getting to know each other. Jingjing introduced Chen Hao to sing in a bubble at sea, and Chen Hao gradually walked out of the shadow of MengMeng. ...

Under the threat of manager Han of Taoyuan Culture, MengMeng became the lover of manager Han, and broke up with him through SMS. MengMeng was ridiculed by his teammates in the boss's bed during practice, which was disgusting. MengMeng couldn't take it anymore, so he cut his wrist and committed suicide. Finally, the manager Han, who arrived, was sent to the hospital.

Guli's idiot band was loved by Mina, a Chinese-American girl, and fell in love with Guli who came to China from the United States to marry Guli.

Their senior brother Gangzi became a broker and took on a big job to hold a cultural exchange meeting. Gangzi invited Gu Li and Chen Hao to do it together. At the exchange meeting, Haohappy saw MengMeng and General Han walking arm in arm, but Haohappy was still heartbroken. Haohappy ran home, and Coulee came to Haohappy's house with MengMeng and asked MengMeng to give Haohappy an explanation. MengMeng said that she had always loved Chen Hao, and Han always threatened her to disagree, so she was left in the cold. I haven't given her anything to do for ten years, and she can't help it. Chen Hao asked loudly and excitedly why? MengMeng received a phone call from Mr Han, asking her to come back early. MengMeng finally wanted to kiss Haohappy, and was hit by Jingjing who happened to come. Jingjing ran away sadly, and Haohappy dropped MengMeng and chased him out. ...

Hai Mo's boss gave Chen Hao a diary, which recorded all the stories of Jingjing and Chen Hao meeting.

Chen Hao suddenly realized that she ran out of the bar and found Jingjing at the seaside. Jingjing swears that if you don't come to see me again, I will become a bubble on the sea with the mermaid. Chen Hao teased her that she had become a husband stone on the shore before becoming a mermaid. Jingjing burst out laughing and the two made up.

Jingjing excitedly showed Chen Hao a newspaper, which was an original singer contest. Chen Hao saw that the image spokesperson was MengMeng. Jingjing was a little depressed, and Chen Hao encouraged Jingjing to attend. Jingjing went straight to the final when she auditioned, and the two embraced happily. Jingjing decided to use the guitar music played by Chen Hao on the overpass and fill in the lyrics to participate in the final. Chen Hao thought it was a good idea and helped her practice the song together.

The game is over. Zhou Mengmeng won the first place and Jingjing won the second place. Jingjing and Haohappy embrace together, MengMeng eyes full of jealousy. ...

That night, MengMeng was insulted by Manager Han, and MengMeng could not bear to escape. He called Chen Hao and was taken home by Chen Hao. In the morning, Jingjing happily came to Hao Hao's residence to find Hao Hao, ready to go to the record company to talk about signing the contract. When she came in, she saw Zhou Mengmeng sleeping in bed. She was heartbroken, called Hao Hao a liar, and then ran away from home again. MengMeng chased out and saw Jingjing being hit by a speeding van. Then, Hao Hao picked up Jingjing covered in blood and took a taxi to the hospital.

In the hospital, Chen Hao knelt down for a doctor. The doctor told Chen Hao that Jingjing's broken liver and spleen could not be repaired ... Chen Hao was crazy and wanted to give her his liver and spleen. ...

Jingjing's last request is to take her to the seaside, saying that her home is there and she will finally be with the mermaid. Coulee took them to the seaside in Mina's car. The two of them sang, composed and wrote lyrics together. Jingjing closed her eyes, and Haohappy's lonely song echoed between the sea and the sky. ...

Mina's mother came to China from the United States to take Mina back. Mina has no choice but to go back with her mother. When she saw her off at the airport, she secretly said to Coulee, I will come back for you. Reluctantly say goodbye.

Coulee looked at Mina's mother and daughter who were drifting away, and her heart was sour. She told Haohappy and MengMeng that she really liked her. ...

Mina's father sponsored them to make records, and MengMeng became a volunteer, often going to kindergartens and nursing homes to teach them to sing. ...
