Smog has remained as a major threat to the residents in Beijing for almost 5 years. In 2013, smog became the center of public debate. However, the issue continued to exist. The picture was taken in December 29, 2017 in my school. The air is still pungent and noxious; the sky is still monotonous and depressive. Smog is like an intangible chain twined over Beijing. It is hard to unlock but not impossible, nevertheless. The key to open it must be somewhere yet nobody knows. It seemed formidable and perpetual so we must strive hard to combat smog.
