If you have a blog in China,you can make money by put ads. For example in my blog(163.blog), i can find the clients who want to put their ads in my blog. I send email to them or just contact the blog
admin of business. They will put some ads in my blog then i just need wait for many toursts click the ads and i can get some money.
But you should remember your blog is good and many people always see your blog if they are free. For example,if you are a Chinese teacher, you teach foreigners Chinese language,you can create a blog to share some Chinese characters and Chinese pinyin in your blog,then your blog is useful and worth.So many beginners of learning Chinese will see your blog. then you can make money.
Please remember don't create a blog with many useless information.
hope to help you guys!
