Galsang Flowers in Blossom was the first science popularization film concerning echinococcosis，which was made by the form of story film. Once the film was available，farmers and herdsmen were organized to learn knowledge about prevention and control by means of intensive broadcasting or watching the film themselves in all regions. In order to evaluate the effect of such popularization，one year later，farmers and herdsmen were investigated for their knowledge，attitudes and behaviors towards the prevention and control of echinococcosis in Xinjiang，Qinghai，Gansu and Sichuan. The results showed that，compared to the baseline investigation prior to intervention，the average scores of their knowledge，attitudes and behaviors increased by 8.4%，16.5% and 15.2% respectively，and the average scores in the above provinces were all enhanced after intervention. It was indicated that the popularization could receive good effect by means of story film in the regions where minority languages were usually used with lower level of education.
