I think the biggest defect of Japanese is that the pronunciation is too simple. Although in the 6th-8th century, Chinese characters came to the rescue, and thousands of Chinese words accompanied with Chinese characters injected great vitality into Japanese, in the 20th century, my ability to cope with new information and new things that may explode more and more in the future was not optimistic. Fortunately, there is a trend in human beings, that is, with the development of human science and technology, the ability of hearing to process information has been greatly ignored by vision. No matter which language is used, it is difficult for the audience to understand and can only watch. So that's why the stamina of Chinese characters has begun to come out, which will only benefit the literate Japanese pronunciation (however, even this depends on other factors, Taiwan Province Province and the Philippines, who can read quickly? Languages with simple pronunciation and no Chinese characters to save the scene, such as New Zealand Maori, are completely miserable. Their vocabulary is extremely long now, extremely long. The most basic problem now is katakana, which is used to express a large number of modern words. The combination of more than 40 words is too low to be recognized and makes people dizzy. Because Japanese pronunciation is simple, Katakana has limited ability to accommodate western words. For example, Katakana can't distinguish between B and V, er and ar in western languages, which leads to a further sharp decline in recognition. If Japanese makes Katakana flood, Japanese will be seriously dragged from practicality to artistry. Anyway, because almost all the local words in Japanese are trained and read aloud in Chinese characters, Chinese characters have become the chapter names of Tale of Genji, all of which are local words, only expressed in Chinese characters: Tonghu, broom wood and empty cicada.
