I will be traveling to China by myself and interested in hiring a person to be a personal tour guide for multiple days ...possibly as long as a month. This will be my first trip to China and my grasp of the language is not so great. Are there companies in China that I can contact that offer multi-day tour guides? I will be arriving in Beijing and plan on traveling throughout China for at least 30 days. I'm not interested in pre-planned tours or anything like that. Just need someone who is trustworthy to show me around who can speak the language and keep us out of trouble.
Short answer, yes, there seem to be. A quick google search for 'private tour guide china' or 'personal tour guide services china' will reveal several, look at the adverts on the right of your results page.
However, for specific examples of private tours, something like Grace China Tours might be what you're after - they have organised tours, but also state:
(grammatical issues are theirs).
They have a live chat where you could quickly find out what they offer.
I'm not sure how much you've travelled, but I have several friends who have been to China, and only two used tours - the others self-explored, with no big problems. Sure there were language barriers, but that's often half the fun. Especially in the cities, you'll be surprised sometimes at how often someone speaks English. Or if you just learn some basic words before you go - bus station, please/thanks and the like, you find yourself with a lot more confidence. However, I can totally understand that that's not for everyone, I just wanted to let you know that it is possible.
Good luck, and enjoy!
