农业合作化运动，从一开始，就是一种严重的思想的和政治的斗争，每一个合作社，不经过这样的一场斗争，就不能创立。一个崭新的社会制度要从旧制度的基地上建立起来，它就必须清除这个基地。反映旧制度的旧思想的残余，总是长期地留在人们的头脑里，不愿轻易地退走的。合作社建立以后，还必须经过许多的斗争，才能使自己巩固起来。巩固了以后，只要一松劲，又可能垮台。

The agricultral co-operative movent has been a severe ideological and political struggle from the very beginning, No co-operative can be established without going through such a struggle. Before a brand-new social system can be built on the site of the old, the site must be swept clean. Invariably , remnants of old ideas reflecting the old system remain in people's minds for a long time, and they do not easily give way. After a co-operative is established,it must go through many more struggles before it can be consolidated, Even then, the moment it relaxes its efforts it may collapse.
