Rather than living a miserable life behind bars like his fellow inmates have done, China's former soccer chief Nan Yong has rejuvenated himself as an inventor and writer, Chinese media reported on Tuesday.

Nan, who was sentenced to 10 years and six months in prison in June 2012 after a nationwide crackdown on match-fixing and corruption in soccer, has invented four devices with patents granted by the State Intellectual Property Office, according to China's web portal qq.com. He has also published a novel while serving his sentence, it said.

In SIPO's online database, four invention patents have been approved under Nan's name by Tuesday, including two devices related to soccer training — a device for shooting training and a portable goal gate.

"To improve the shooting power and accuracy of soccer players, this device, which features pressure-sensing pads installed on the gate, could mark the goal placement on the gate area while rating the shot's power, to guide players to improve their skills," Nan noted on the patent specification for the shooting equipment.

The portable goal gate is made of lightweight detachable parts and could be transported anywhere to be reassembled for soccer games and training at a low cost, according to the patent papers.

Of Nan's four patent applications, the other two are a mobile phone kickstand and a device to control multiple desktop computer monitors were submitted last December and granted this year.

He has also been concentrating on writing in prison and published science-fiction story about a lonely priest under his pseudonym, Wen Yan last year, Beijing Youth Daily reported.

Citing Nan's good behavior, including inventing and writing, Yancheng Prison recommended to Beijing No 2 Intermediate People's Court on Nov 13 that his sentence be reduced.

The court approved the request this month after receiving no complaints during a public review in November. His sentence will be reduced by one year, Nan will be released in July 2019.

The former vice-chairman of the Chinese Football Association was imprisoned in 2012 for accepting bribes worth more than 1.19 million yuan ($191,900) for fixing matches and illegally using his power in exchange for economic benefits. Nan was also fined 200,000 yuan.

Nan's turnaround from a corrupt official to an inventor sparked heated debate on Chinese social media on Tuesday.

"After all, he's shown that he loves soccer. He was just blinded by the desire for money," a netizen Robinlovesellen wrote on Tuesday.

Another netizen, Shixiaofeng, wrote, "I strongly recommend that all the soccer governing body officials in China work in jail so that they will be forced to make a real contribution to the game."

During the Ministry of Public Security's 2010-to-2012 campaign against soccer corruption and match-fixing, 59 officials, players, referees and club owners including Nan and his predecessor, Xie Yalong, were put behind bars.
