Mr Zhou Kai (right) told a court in China that his daughter Xiao Nan turned on him and his mentally unstable wife last year after she started her first year at secondary school.
He said that his daughter would demand that he buy her K-pop boy band EXO's memorabilia and tickets to their concerts even though they were poor.
When things didn't go her way, she threw tantrums, damaged four mobile phones and one computer and refused to eat or go to school.
According to media reports, Mr Zhou had a heated argument with his daughter before he attacked her.
He had told her: "Please don't only think about chasing your idols, no matter how good they are, they will never be better than your parents.
"If you continue to chase them, they will affect your studies, do you understand?"
Replied Xiao Nan: "I just love my idols, the love I have for them is stronger than the love I have for my parents. Idols are much better than you (and mum)."
Mr Zhou rushed into the kitchen, took out a chopper and put it on the living room table.
Said Mr Zhou: "At that time, I just wanted to scare my daughter.
"But she came up to me and used her fists and viciously hit me a few times and repeated again that 'Idols are better than you parents!'."
He said he took the chopper and hacked her till she fell from the sofa to the floor.
Mr Zhou then slashed his left wrist but was discovered before he bled out.
He told Chinese media: "At that time, after I hacked my daughter, I wanted to save her but it was already too late.
"It was when she said that her idols were better then me and my wife that my heart went cold. I felt that why not we (my daughter and I) just die together and get this all over with."
