Abstract: In 1981 the National Cooperative Research Team for Handednesshad for the first time investigatied the Jinuo distribution of leftand right handedness. Results showed that the Jinuos were all ex-treme right-handed which is a very special conclusion. To verifythis conclusion, in 1989 we once more investigatied the Jinuo'sdistribution of left and right handedness, it was found that the Jinu-os were not all extreme right-handed, consisting of ordinary righthandedness, mixed handedness, and left. handedness, and even1.79% extreme left handedness among them. The Jinuo's left han-dedness rate is highor than the Han's, but the rate is close to other minorities. This might have connection to their traditionalculture. The left handedness rate of Jinou leans on the high side.Therefore the investigation results by the National CooperativeResearch Team for Handedness in 1981 must be corrected.

Key words: Jinou, left and right handedness, re-investigation
