Abstract: In order to understand the situation of the primary and secondary school students' flat-feet occurrence in the region where minority nationalities inhabit,the routine method of footprint is adopted to make the selective examination into the students coming from the Suma Village of the Laershan Town of the Fenghuang County at the junction of Hunan and Guizhou Provinces.The investigation results show that the rate of boys' flat-feet occurrence is higher than that of girls';the younger the students are,the higher the rate is;the rate of the left flat-feet's is obviously higher than that of the right's.

Key words: region where the Miao nationality inhabits, primary and secondary school students, bowfoot, flat-feet
