Translations are all over the place. 

The German and Korean translations are about Standard Mandarin tones. The Japanese and Chinese ones are about the four tones, and the English and Serbian ones are about tone names. I have copied non-redundant content about Vietnamese from this article to Vietnamese alphabet. I will proceed to put most of the content about Chinese into the article four tones and link to four tones and Vietnamese alphabet from this article. After that, I will try to make translations correspond to each other.
