A colombian-japanese entrepreneur Yokoi Kenji, spoke in the beginning of 2015 about the way Westerners assume about asians from the Chinese Empire.
Maybe it's not a movie or TV series, but it's better than one, or so it seems.
He was talking in Colombia about what the word discipline really means, which is often confused with other things, and debunking what is often misrepresented in the West (i.e., in America) about the Chinese, Japanese, Koreans, Thais, etc.
When I was in college, I was shown a video in class that I like. This brilliant man recounted his experience upon arriving in his country, how people, even children, who asked him about his lifestyle judged him based on his ethnicity and assumed he ate rats, cockroaches, dogs, snakes or other animals. And telling things about his past when he was children and go to Japan and enrolled in a school or when he went to other countries.
One of the things that also stands out from his childhood is that his Colombian grandfather said that Japan was the master of technology (thing that he thought and traumatized Kenji). When he went to Japan for first time and school, he saw that the life is the same, with the only difference that japanese are more disciplined, they're more punctual; they're never late. They let you know when they're going to be late and also when they're going to miss something.
He touched on the topic of something that happens frequently, that any people in the Occident has said "Japaneses are smart" egocentric phrase, that looks like "women are more intelligent than men" or "Colombians are hospitable" generalizing phrases, which are the triggers, or rather the chains of misrepresentations about the lives of certain people, a country, a policy, or something else.
What the entrepreneur really wants is to raise awareness about how our personal opinions end up affecting and creating reputations that distort realities and truths. Whether it's because some make comments that spread to the rest of the world, or because others, driven by common sense, promote what they assume about someone, a group, or, above all, an entire country. In this way, they either harm or compliment the aforementioned characteristics.
