The results of this research were as follows. The percentage of the right type on six traits was much higher than of the left type, except for arm folding. There was no sexual difference in the Tunpufor the seven traits preference. Compared with other ethnic groups, the percentage ot K-K type of foot preference and arm folding were at the middle level, whereas the percentage of R-R type of leg folding and hand clasping was at the highest level.
