Gambling is such a popular pastime in the Pearl River Delta that shops selling casino equipment and various punting aids have opened up on some of Guangzhou's busiest streets.
Goods for sale include baccarat tables, slot machines, chips, marked cards, 'X-ray' spectacles, 'magic' dice and software for creating online casinos.
'We have everything you can use in gambling,' one shopkeeper said. 'It's important that they help you win.'
Part of Huanshi West Road, near Guangzhou Railway Station, looks like a dream destination for poker machine players, card sharps and baccarat cheats, featuring 10 such shops in a wing of Tianma Mansion, alongside convenience stores.
They are less than 50 metres away from a police station - the Yuexiu district plain-clothes investigation department.
Guangzhou police have been cracking down on illegal gambling. An officer familiar with the crackdown said gambling dens and small underground casinos had flourished in delta cities such as Guangzhou, Foshan and Dongguan, especially since the central government tightened the curbs on mainlanders visiting Macau.
