It's useful improvement, thank you. I have to review this some time.

Is this machine translation? What you can tell about this translation?

[wordpure]

I translate with the help of i18n-ally, some strings are machine translated and then touched up.

langCode mainly refers to the Chinese Wikipedia of List of ISO 639-1 codes and the name of the corresponding language in the Chinese Wikipedia.

In addition, I have paraphrased some of the words and phrases based on my personal understanding of the context of the text.

What I changed in commit Fix and optimize langCode is as follows：

• Fix spelling errors in Sichuan Yi and Kuanyama
• Fix for Interlingue and Interlingua, Norwegian Nynorsk and Norwegian, which were translated backwards
• Revise the translation of Afrikaans, Chichewa and Quechua to more commonly used language names within China
