Actually, I’m a chinese. And I have lived in beijing for more than 20 years. I like the city as I was born here. If you like it too, I’ll be happy.
To tell the truth, Beijing is a little dirty for it contains so many people. The population is so large that you can’t imagine. And the atomsphere is not very well too. So if you want to come here, first, you have to think that if you will be allergic to the dirty air. If not, that’s ok.
Despite of it, the city is beautiful, and has many interesting places. You can know much more about chinese culture, and also china’s new development. You’ll like it, anyway.
