I don't like Beijing!

My fifth day in Beijing. My impression is...it sucks! I hate Beijing! I don't wanna stay here. Everything are dirty! Everywhere are dirty (except the Microsoft office, to be fair). I couldn't understand why people can live here. Street smells. Foods are dirty and oily. Cooks deomonstrate their dirty cooking precedure in front of customers! People and cars cross the road without following the traffic light! And...ai...you name it!! Ridiculous!
