Right again Jim
Actually Shanghai (PVG-Pudong) and PEK are like western cities compared to places like Haikou but definately you get the idea as far as the Mainland compares to Taiwan.
They're pretty soft on foreigners in Haikou which makes it a pleasant place to live. Haikou is still business, Sanya is the Tourist haven. Yalong Bay in the South East is beautiful (But 2-3 hours drive from Haikou)
The only problem is some foreigners lose control of themselves here.
You get to hear some pretty spectacular stories which are incriminating, so I'll save them for a fireside chat, a good red and lots of laughs. Not for a public forum.
