High Quality Content by WIKIPEDIA articles! In the Vietnamese language there are two sets of numeric systems, based on the Native Vietnamese and Sino-Vietnamese names of numbers.Among the languages of the Sinosphere, Japanese and Korean both use two numeric systems one native and one Chinese-based and use the Chinese-based one more commonly. In Vietnamese, however, the Chinese-based system has still not reached everyday use. Numbers from 1 to 1000 are still usually expressed in the Vietnamese system, and only a few numbers (such as 1,000,000, tri u) are expressed in the Chinese system.
