Why did Lu Zhiang go to prison before the summer solstice?

Before the summer of solstice, Lu Zhiang injured someone who framed Fu Xiaosi for plagiarism, and was subsequently arrested and imprisoned. Lu Zhiang has been a good friend of Fu Xiaosi since he was a child. He is extroverted and likes to drink coke.

Lu Zhiang, like those lonely leading men in youth movies, always wears undeveloped clothes, unbuttons his school uniform, bares his chest and reveals his white shirt, and runs amok in school with a backpack. After her mother died, Lu Zhiang, who grew up overnight, became tough and quiet. At the end of the story, Lu Zhiang seriously injured Fu Xiaosi's opponent at the press conference and was sentenced to life imprisonment.

Extended data:

When Lu Zhiang was a student, she was very noisy and always had a sunny smile. And many blows in the process of growing up made him calm, gentle and tolerant. He is like a doomed angel, guarding Chang Xia and Fu Xiaosi.

Lu Zhiang actually left everyone to study finance in Waseda when he was at school. But later, Fu Xiaosi and Chang Xia set up their own studio, and Lu Zhiang returned to China at the invitation of a friend. However, because of the plagiarism in Fu Xiaosi art exhibition, Lu Zhiang directly beat the plagiarist to pieces at the art exhibition, and finally began to flee, and was finally arrested and sentenced to life imprisonment.
