You couldn't drag me to China if you gave me an all expense paid vacation... *shudder*
Now... if it was Italy I'd jump on it... love the food, the architecture, the language, and a good portion do speak English simply because in Europe being multi-ligual is totally normal. Sanitation is also a big plus. Good regulations on food, etc. SAFE.
If it was my child, I wouldn't even try to force them into it... (actually I'd prolly try and talk them out of it simply because I'd go crazy worrying about them... but that's me being paranoid, I worried like a fiend when my son went to camp in New Mexico for two weeks.) Your folks are NOT the one who'll be stuck over there totally alone, no support, and you can't just call mom and come home if you have a nightmare. Seems pretty crappy to me that your parents would just ignore all that and even try to push this on you.... have they read about China lately? Even the 'good stuff for export that has to meet snotty US standards" ends up being toxic... why would you want to go there, much less LIVE there for a year?
Sorry, bit of a ramble there... but I agree with you 100% your feelings should be the ones that matter most. If you aren't comfy for whatever reason than DO NOT GO. Stepping back now will be a LOT easier than later. Going with your gut is always the smart route IMHO.
