Beijing police have registered more than 80,000 employees of the city's public recreation centers and bathing services this year in an effort to clean the industry, Xinhua reports.

A database has also been built based on the real names of the workers. Each of the registrants received an IC card as a permit to work in the industry. Besides personal information, the card can also record the working hours of the cardholders.

The city's public security forces have reinforced the crackdown on prostitution business in the industry this year. Police has visited 2,635 recreation centers since July and suspended the operations of 42 places that did not complete the worker registration.

According to police figures, the illegal sexual cases in Beijing fell by 61 percent in July compared with the same period last year.
