When Turkic-speaking Tabghatch conquered China in 386 CE and ruled her for nearly 200 years, they, being minority rulers, chose to adopt the Chinese writing system and language as the official way of communicating with its subject population. They finally also took over the writing system to write the Turkic language for their Turkic population which led to a Xianbei National Language (XNL). This work describes 7 cases of Turkic-rooted Sinitic functional expressions, all featuring the word 的 [d-], supported with historical citations in Chinese documents, believed to be cultural continua of the XNL.
