I dunno what planet you are living on but China stopped being Communist 20 years ago, now its hyper capitalist and you'd have a better chance of a business succeeding here than in America land of the broke. Don't listen to all that small business cheerleading BS... its fvcking hard to get a successful biz going. If you don't have a J O B then you better have a ton of C A S H saved up to carry you for a year or two. Depending on how new you are to small business, it could take you a good year or two before you actually learn how to network and get setup. Expect that you will initially not make ANYTHING.
I've started 2 small businesses that I pumped tons of money into, only to run into small snags that completely toppled my plans. The 3rd one I started did fairly well only because I'd made so many mistakes beforehand on the previous two. The 4th is doing half decent but having a JOB making money for someone else is much easier and less stressful.
You forget to factor in the sheer amount of marketing work YOU have to do FOR FREE... unless you are selling some crazy hot new invention that people are begging for or have some super hot service that people need, then you are going to have to bust your ass FOR FREE. You are going to get snubbed A LOT, told to FOFF, have people shut doors in your face, you will have to be very think skinned. The best thing to do is to approach that sort of thing cautiously and on the weekends to start... once you build a customer base and your weekends are completely full of work hours, then you can consider expanding into your job space. Trust me mate, it sucks living with 0 dollars and having to move back into your parents house cause your business idea tanked.
