Chinese, also known as Mandarin, was the modern Chinese spoken language used in mainland China on Old Earth. It was one of the major languages spoken in the Andermani Empire.

The phonology of Standard Mandarin was based on the Beijing dialect of Mandarin, a large and diverse group of Chinese dialects spoken across northern and southwestern China. The vocabulary was largely drawn from this group of dialects.

Many Andermanis had Chinese first names, combined with a German family name. (HH6, HH10)

The langauge was the source of the nickname for the Quintet.
