(3) Correctly grasp the guiding ideology and dialectical relationship between praise and criticism. Comments on people and things are always inseparable from praise and criticism. Praise and belittle, praise advanced and criticize backward, the two are always the unity of opposites. As far as the relationship between the two is concerned, praising the advanced aims at encouraging backwardness and promoting righteousness, and praising the advanced itself is precisely criticizing backwardness and eliminating evil. Criticizing backwardness is precisely to turn it into advanced and achieve the purpose of criticizing individual education. At the same time, advanced and backward always exist in unity. There are backward factors in advanced things, and there are some advanced factors in backward things. Therefore, when commenting on people and things, whether it is praise or criticism, we should try our best to embody the principles and requirements of seeking truth from facts, being properly measured and moderately praising and criticizing, and we must never be absolute, simplistic or emotional.
