In the past, this has made problems with the communication, with the Mandarin, Mongol, Turkic, Tibetan, and many more languages being very different from one another, so the people were not able to understand each other. Over time this has changed though, and as China became the country that it is nowadays, an official language was implemented and everyone was obligated to use it as official language, while the languages used regionally remained to be used as secondary languages.
