Biophotons from three healthy subject's hands were measured every Friday for one year. The correlation coefficients between the left and right palms were found to be 9.0, and a similar value was also obtained between the left and right back of hands. However, the correlations between the palm and back of a hand turned out to be low, on the average only 0.5. These results are consistent with the result of Zhang's $CO_2$ production rate experiments on the acupuncture points. The high correlation between the left and right, and the low correlation between the palm and back are interpreted according to the acupuncture theory of meridians. The palm and the back correspond to the yin and yang meridians, respectively. And their behaviors are rather opposite, thus they show low correlations.
