Gao Xiaosong was born with a silver spoon in his mouth. His grandfather was headmaster of the famous Tsinghua University. His wife’s father graduated from the Imperial College London and founded Shenzhen University. He basically grew up on Tsinghua's campus, and studied in the top schools in China, before he, unsurprisingly, entered Tsinghua's electronic engineering department, one of the school's best majors.
He wrote On the Same Page as You are at age 24. Almost overnight, every young person knew the song by heart. That tune and his later works made him a household name in the country. He later became a judge on the hot variety show (综艺节目) China's Got Talent.
Everything has gone right for him aside from one major bump in the road—he was arrested for drunken driving in 2011, after he left the first press conference for his film, My Kingdom.
"For me, the six months was not only a result of the trial but also an atonement,（赎罪）" he says. "Six months is like a leaf falling from the tree of life—no big deal. I was a spoiled person in many ways before 40. So, maybe it was an opportunity to pay for my wildness and arrogance(傲慢) in my youth." The hardest thing for him in prison wasn't sleeping between a thief and a bad man but missing his daughter's development from ages 3.5–4.
Gao has become even busier after getting out of prison for drunken driving. A tour concert of his songs is going around the country, while Morning Talk airs weekly. He is searching for new vocal talent for a music company, and his next film is in progress. But he knows clearly what he wants from life—he plans to focus on music until he turns 60, after which he'll focus on writing and film directing. "You can never write pop music at 60," he says. "I don't complain about that. But you can always write a good book or direct a good film, no matter how old you are."
