The Communist Party of China once devoted themselves to the construction of health medicine in the Shaanxi-Gansu-Ningxia border region,and carried out rich health communication activi-ties among the masses.Based on the theory of practical discourse analysis,this paper cuts into the spe-cific content of healthy communication activities at that time from three aspects:text,visual and sound texts,which together constitute multimodal discourse expression under the background of revolutionary political narrative.This kind of discourse practice forms a daily mobilization mode in the health move-ment and diversified propaganda under the leadership of politics.The three main topics,namely,the is-sue of women and babies,the anti-witch movement and the cooperation between Chinese and Western medicine,reflect the social value construction process of modern enlightenment and organizational transformation.The conclusion points out that the health communication activity in Yan'an period was a cultural movement in the form of social mobilization,and it was of direct guiding significance to the health work policy in the early days of the founding of New China.
