Actually I think the term ŸcŒ}"›{KŠ¿Œê or'†•¶" is better. This is becauseš Œê means the national language of the country. So for the Japanese their š Œê is Japanese, for the French their š Œê is French and for the Australians their š Œê is English and so on...
I prefer 欢Œ}Šw习'†•¶/, Š¿语because literally '†•¶ means the Chinese literature/language where as •'Ê话 literally means common language.Š¿语 means the language of the Hans which is another good choice in my opinion.
