RUDONG: Rusty padlocks seal empty classrooms and blank graduation certificates litter a dusty, silent school corridor in Rudong, a haunting glimpse of China's ageing future in a town which pioneered the one-child policy.
Education facilities are being shrunk to cater for dwindling pupil numbers, and the once bustling Technical Secondary School is now a hollow eight-storey shell.
Long before China's Communist rulers rolled out the one-child policy nationwide to halt population growth, Rudong was already carrying out forced sterilisations, abortions and highly personal checks on women on its own initiative.
It was praised by the authorities for its strict enforcement of the rules that became the cornerstone of Beijing's social management.
Now China is facing the consequences of a dwindling workforce and a rapidly ageing population, and Beijing has been loosening the rules to encourage more births.
But those who enforced the drive a generation ago in Rudong, in the eastern province of Jiangsu, remain proud of their work today.
"There was not a single teacher in our school with more than one child," said Shi Dejun, a retired doctor who was responsible for checking female staff members at the now abandoned school.
"Rudong is China's model for family planning, and this school is the model for Rudong," he added, standing on a disused playground littered with shards of glass and weeds burrowing through cracks in the concrete.

China has long defended the one-child policy as a key factor in the country's rising prosperity -- sentiments echoed by Shi.
"Most of the young have the opportunity to work overseas or in developed cities like Shanghai because of the one-child policy," he said.
But Chinese experts expect the country's working population -- estimated by the government to be roughly 915 million at the end of 2014 -- to drop by around 40 million by 2030.
By 2050, 30 percent of Chinese will be 60 or over, the UN estimates, versus 20 percent worldwide and 10 percent in China in 2000.
