So I was reading this: Asia’s Orthographic Dilemma. I don’t have any reference in linguistic, although I did have some lessons at university, so I don’t even know if this author is legit or not. I have forgot the majority of what I have read from this book already. But the things that I learn from it is not its strictly speaking content anyway.

• He said something about Principle of Substandard Southern Speech, basically according to this, Saigon speech, just like the one of Nanjing or Kyoto or any big city in the South of any country could never rival with the official speech of Northern cities like Hanoi, Beijing or Tokyo. So being in the South means you will stuck with an image of an unsophisticated culture forever. This sounds BS, especially when he never elaborate. It seems like this is just some observation without proper demonstration and explanation. And they, the scientists, even have a glorious name for it.
• Languages are living things. I kind of know it already, but now I realize that it is not always progressing, it can deteriorate and die. Writing is tied to speaking language, so it changes accordingly as well, albeit much more slowly as it is institutionalized. An weak writing system with too many flaws could actually affects the speaking language.
• Vietnamese writing system is far superior to Chinese and Japanese writing systems. They really should change it to a more logical one. Yes, of course, nothing is perfect, including writing system. But in my opinion, language is speaking first, so the writing system should follow closely the speaking.
