I agree with steve.
I am a social worker and I have seen the difficult lives led by the homeless. Your thinking seems delusional to a degree, but obviously a person cannot get a full assessment on the internet.
Coincidently, hermits are solitary by nature. If you had a friend with you, you would simply be poor and living in a cave, which I'm sure the Chinese would not like.
What are you going to do for food? What if you get sick or injured? If you want to experience life as a homeless person at least do it in your own country first as I assume you understand your nations laws at least a little better than China's laws.
What exactly do you expect out of this lifestyle?
Well basically what I am planning to do is to make a big step away from modern life style and towards living with nature.
I do not plan to completely separate myself from civilization, I simply want a life way closer to nature, with as few material holdings as possible.
Means I will be more or less near the village, able to walk in for food or opportunities to earn a little money, but far away enough to be surrounded by nature I can enjoy while practicing MA.
As for the difficulties, I am mostly concerned about wildlife and possible infections or injuries, no health insurance and maybe no doctor near either. But for me, MA not only means self defense, art and health, but also overcoming my own fears and surviving challenges.
Accepting the possibility to die any second is part of my MA philosophy, and lets be honest, no matter where you life, it could happen just about anywhere.
I am very aware of the severe conditions, especially in China.
People may wonder why I seem to make things so difficult for myself but that is part of my philosophy.
I spent most time of my life with learning and experiencing different cultures, philosophies and religions, as well as a really rough childhood which nearly killed me.
I have experienced both, the convenient life as well as the kind of life you better avoid if you plan to stay on this world, and I found the only way to be deeply satisfied for me is with a certain amount of poverty and distance to modern, shallow life style.
