Beijing's Jekyll and Hyde fight for better air quality

In Robert Louis Stevenson's classic The Strange Case of Dr Jekyll and Mr Hyde, the good Dr Jekyll fights with the evil inside him, which turns into his split personality, Mr Hyde.

Through the pages of the book, the battle wages on. Jekyll has his victories but in the end Hyde overwhelms him and the goodness of Jekyll is lost forever.

It might seem strange to you but it reminds me of Beijing's battle with pollution.
