Objective To develop Chinese static happy, angry, surprised, fearful, sad, disgusted and neutral facial expression photo gallery for future emotion research and to find out a better method for good facial expression picture acquisition. Methods People were grouped by pre-school age, school age （ primary school age, middle school age and academic school age）, young people, adult and aged people between 5-year and 80-year-old as the actors showing different facial expressions. Before taking photos, they knew the purpose and agreed to sign the consent. Firstly, all people were standarded to be trained to know the meaning of seven facial emotions, the grades and facial characteristics of seven facial emotions. The facial expression photos were recorded by the same examiner in the same lab. All photos were taken by using Canon IXUS 50 and SAMSUNG $850 under the same mode, and the primary photo gallery was made. Then research team members picked out the well-taken photos to be processed as 10 cm - 15 cm facial expression pictures. 60 Chinese university students were asked to identify emotion category in these pictures. Seven pictures of Japanese Female Facial Expression （JAFFE） were used to identify the validity. The pictures were picked out and processed by 28 university students to test their reliability , and to test their validity compared with JAFFE. Results 80 pictures were picked out in the first screening. One evaluator was ruled out because of his anxiety and depression, and 59 students （29 boys and 30 girls） screened out 40 pictures, whose discrimination rate was higher than 70%. 21 pictures were picked out to be tested for reliability, validity and emotion grades. The discrimination rates of 21 pictrues were higher than those of JAFFE. Besides pictures angry 1, angry 3, fearful 1-3, sad 3 and disgusted 1-3, the reliability coefficient of the others was higher than 0.7. Compared with JAFFE, the consistency of negative facial expression in 21 pictures was less than the consistency of happy, neutral or surprised facial expression.
