In 1964, China announced to an astonished world that it had abolished prostitution - which had flourished in the Middle Kingdom for more than 2,000 years.
People marvelled at, then praised, the 15-year-old republic's 'miracle'. But China had spoken too soon.
Since then, the world's oldest profession has made a dramatic return, a side effect of 20 years of Deng Xiaoping's reforms, wiping out one of the proudest achievements of the communist state.
Official figures published this week show that police across the mainland arrested 250,000 prostitutes in 1997, a 20-fold increase over the 12,281 detained in 1984.
The number of women working in the profession is now estimated at between 800,000 and 2.5 million.
Police divide prostitutes into seven categories, from high to low-class.
