Yangshuo is a blast. One of the top-10 most beautiful cities in China. Tons of horny galls too. Past bus station on the right. 20+ places. 150 RMB for full service. bargain hard. Lots of nasties and some hotties. Find one you like, get her number and she's yours all week. Again: 150RMB, but they'll ask 300. Do the walk out and watch what happens when they chase you and say Ok 150.
Tai guile (pronounced: tie gway leh) means "too expensive". Use this phrase often and liberally. The locals love it because they use it too ALL the time.
You think the service would be less when you bargain, but its not. You get the same no matter what you pay. These girls are mostly for the Chinese tourists though, wear a Jimmy always with these girls, and 90% of the Durex's sold in China ARE fake 4-sure. Only buy from Carefour or Walmart, etc.
