can native English speakers help me polish my language?

Maugham in his works mentions this black drug for many times. The most common sight is that most Chinese, be they man and woman, coolies and peasants, officials and grassroots, old and young, lie in bed, hold a opium pipe and are indulge themselves into the drug which will finally destroy their health and spirit. Those opium smokers are thin, dark-faced and lack of energy. The image of “Chinese people are numb opium smokers” represents the classical image of Chinese people then. There are multi-fold implications in this image: inertia, numb, stagnating, stupid, degenerated, weak, and evil and so on. (周宁 201) Ku Hongming may be the most striking example. When Maugham saw the philosopher Ku, he was a black, thin man with a pair of hands just like the animal’s paws.
