There are many ways to make money online. But I just give some ways that I have already tried. The first one is by creating blogs / websites. You should be a good writer that could attract a lot of readers to read your blog.
You could use wordpress.com or blogspot.com for a start. They are all free. With blogspot.com, if you have at least 1 English blog, you could apply for Google Adsense. There you could get money by placing ads in your blog. You could create other blogs and put the Google Adsense there. If your blogs get around 1,000 pageviews per day, you could expect US$ 20-30 / month. You could not support your family, but you could buy and eat Chinese meatballs with it... :)
