Ideally I'd want some kind of fund holding a lot of stocks. Individual companies are too volatile for me. I tend to buy high and sell low when investing in individual companies.
If you want to play with A shares, it is almost day trading on individual stocks and the Chinese stock exchange isn't sophisticated enough yet where people actually go and buy funds. Of course, foreigner individuals are mostly locked out of A shares, so this is mostly moot, maybe try Hong Kong?
