In Mandarin Chinese, these are called Gǔ Zhuàngzì or Fāngkuài Zhuàngzì (; "square shaped Zhuang characters"). Sawndip (Sawndip: ) is a Zhuang word that means "immature characters". The Zhuang word for Chinese characters used in the Chinese language is sawgun (Sawndip: 倱; lit. "characters of the Han"), gun is Zhuang for the Han Chinese.
