Nowadays, American TV dramas are very popular among the young audiences around China and even around the world. In some of the hit American TV dramas, however, the tendency of post-colonialism can be easily found. In these dramas, the image of oriental countries especially China is just imaginary and thus is distorted. Though these dramas objectively depicts a Third Space which is the result of simulation and mixture, and which is both different from oriental culture and occidental culture, the Chinese or the American Chinese in them are generally in the position of subordinates, and thus almost have no say. The tendency of post-colonialism in the American dramas may mislead the young audiences in China, making them form false beliefs about China, Chinese and Chinese culture. Fighting against the tendency of post-colonialism is not only the task of audiences but also a great project that policy-makers and cultural researchers must devote lots of time and energy to.
