For those who want to know, Dongguan used to be infamous for prostitution - think 50-100 (literally) of girls in spa's, clubs, KTV''s, hotels, where you can select girls to party with you, go dancing, sing, drink, etc... at larger establishments and especially at hotel, they have club/spa/ktv all-in-one. And at any time you can take a girl back up to your hotel room for some more private fun and then come back and continue to party and then take another girl back up later; or you can take a girl or girls back up at the end of the night and spend the night in your hotel room - all at a low cost. But then China government cracked down on the city and many of the places closed up - but they have made a comeback in recent years but they are much more hush about things now.
But in that city, they offered what we call here Dongguan Style services at NO ADDITIONAL COST, which is essentially an erotic experience using techniques dating back from ancient China. The full technique includes a large number of sexual activities all aimed to pleasure and worship the man. But this was a specialty that only select girls who have been trained can do as it also involves a certain amount of artistry and choreography - the vast majority of girls will do the common DG services which includes: fire and ice BBBJ, wind and fire BBBJ, nuru massage, rimming, prostate massage (if you like that), MSOG and CIM. The highlight of DG style service is definately the wind and fire BBBJ but now all establishments has the equipment for it - think of it as spinning blowjob while suspended in the air.
Here in North America, DG style usually just means fire and ice BBBJ, dry nuru, rimming, MSOG and CIM, however there has been a couple of shops recently in Toronto that are offering a more fuller DG style service with the wind and fire BBBJ but i don't expect any girls to be able to do it well.
