To the responsible comrades of all provinces, autonomous regions, and municipalities: If you concur, please circulate this article to every agricultural cooperative for reference and encourage them to follow suit. It should be noted that Yanggu County is the hometown of Wu Song, the tiger-slaying hero; yet in this area there has traditionally been no practice of pig-raising. This cooperative, however, broke with that custom and began raising pigs. The first year was a failure, but the second year brought success, the third saw further expansion, and by the fourth year there was rapid growth, with an average of about two pigs per person—totaling 20,000 head. If this cooperative could achieve such results, why should other cooperatives be unable to do the same?
