There's the occasional police raid too in Hong Kong.
Which I don't understand Discos, saunas, bars, and video game arcades. Checking for bullshit ID and drugs. Keep the peace, so to speak. Sure the police are relatively civilized but they are authorized to lay the smack on you with their batons if the crowd gets "unruly". If dumbass triads and street punks try to be tough and provoke the police, the police will indiscriminately beatdown everyone. Not a pretty sight but nowadays kinda rare.
What an unfortunate event
It's a publicity move to show the police is
always in charge But raiding saunas and vice dens is the least problems in CHina. Heck, there's still the June 4th Tiananmen square incident and forced abortions to instill 1 child policy.
On the bright side, since the police already "did their job", it's actuially safe to go punting in other areas of Henan. Fewer girls but the chance of getting raid is almost 0!
Shit like this probably won't happen in Dong GUan or Zhuhai unless something really bizarre like the Japanese Gangbang incident occurred again - there's already a large vested interest for the authorities. Unless it's anti-corruption sweep Chongqing style!
