The killer targeted young women wearing red and followed them home, where he would rob, rape, and murder them.
"To satisfy his perverted desire to dishonor and sully corpses, many of his female victims' corpses were damaged and violated", the court said on Weibo when he was convicted.
He reportedly also mutilated the bodies of his victims, including one girl age eight.
Gao's family seemed to have been in the dark about his crimes.
"He's reclusive and unsociable, but patient", police said at the time while announcing a 200,000 yuan reward for information leading to his arrest.
Police began investigating and eventually zeroed in on Gao, who was registered as living in his hometown of Qingcheng, located about 120 km away from Baiyin, where he had found work at a local vocational school and was the father of two.
The original Jack the Ripper is believed to have murdered and mutilated at least five women in east London in 1888.
"I didn't know what to say, or how to deal with it", he said.
The series of murders by Gao Chengyong, 54, over 14 years haunted the city of Baiyin.
The trail of bodies ended in 2002, as Gao suddenly stopped preying on women.
Police had been searching for the killer for years before his arrest in 2016.
Dubbed the Chinese "Jack the Ripper", Gao killed 10 women and one girl between 1988 and 2002.
A DNA sample from the uncle linked to evidence from the murders, with cops determining that the killings were committed by a relative. Gao told police that he killed the woman because she had caught him during a robbery attempt. China's supreme court had approved the execution, it added.
