This paper is to introduce the history and achievements of research on tongue moving types, the frequencies of rolling, folding, twisting, clover leaf and pointed tongue in different human groups and current studies by Chinese researchers.

A sample of 309 middle school students(120 males,189 females)of Mulam was investigated on five tongue moving types including tongue rolling,tongue folding,tongue twisting,pointed tongue and clover-leaf tongues.

The results revealed as follow: 1) No significant sexual difference was found in the frequencies of five tongue moving types;2) Some interactions occured between rolling tongue gene and pointed tongue gene,and also interaction occurred between rolling tongue gene and clover-leaf tongue gen.

In the past,their relations were discussed from their definitions and mechanisms,the study dedicated tip-of-the-tongue are merely strong feeling of knowing.

Some came from the dental fricative initials of proto-Tibeto-Burmese,some came from SC and CS clusters of proto-Tibeto-Burmese,and others came from the other kind of the clusters of proto-Tibeto-Burmese.

There are conversions between highlight dental and blade_palatal complete change,apical intermediary tone,apical make tengue side and apical retroflex and so on.
