advice: overall

maybe you're wondering if you should take a trip to asia. here's some thoughts to ponder to pre-screen yourself:

Hong Kong: anyone can enjoy.
Taiwan: great. taipei has anything you'd find in a big city. rest of island is beautiful with many undeveloped areas, such as the east coast. lots of unobstructed coastline and cultural treasures at the national palace museum.
China: not for the faint of heart, but it depends on the area you visit. we were always in SEZ's (Special Economic Zones), which are the designated areas the communist governement decided to give capitalism a whirl, so they cater to tourism. still , most tourism is targeted toward chinese and japanese so don't expect Western standards. even shanghai and bejing are a little rough around the edges. low costs once you're here though, so that helps balance things out. if you're a camper you could handle south china, but if not i'd stick to the shanghais and beijings. you will run into 'hole in the floor' no matter where you are, so be prepared. carry your own TP at all times.
