I haven't known many people doing hitchhiking in China, but I know this is possible, so if you are crazy enough I am searching for someone who would like to accompany me in such adventures during the weekends.
I cannot promise we will catch a ride, because I do not know is it possible.
I cannot promise I will be able to communicate well in Chinese because I have just small notion of this language.
I cannot even promise great fun, because I have no idea will it be like this.
However, I can promise going into unknown, at least for me.
