There are many contradictions in life. To solve some practical problems in life, we must deal with the primary and secondary relations of contradictions, which is universal. First of all, we must solve the main contradictions, and then solve the secondary contradictions one by one, so that things can develop smoothly. To distinguish between primary and secondary contradictions, first of all, the main contradiction plays a major role in hindering the development of things and is in a dominant position, which will lead the development direction of things. Secondly, secondary contradictions are in a subordinate position. It does not play a leading role in hindering the development of things, but plays a promoting role. Third, there is only one principal contradiction, and there can be multiple secondary contradictions. Fourth, the principal contradiction and the secondary contradiction can be transformed. When the current principal contradiction is solved, the original secondary contradiction will immediately rise to a new principal contradiction, and new secondary contradictions will appear constantly.

Therefore, when solving problems, we should focus on dealing with and solving the main contradictions, and secondary contradictions cannot be ignored. Only by properly handling the primary and secondary relations of contradictions in time can we effectively solve some practical problems.

The primary and secondary contradiction is to distinguish the mainstream and tributaries and judge the nature of things. For example, everyone has advantages and disadvantages, but why are there good people and bad people? This is the primary and secondary aspect. Good people are only advantages, the main aspect of contradictions, and the mainstream; However, shortcomings are secondary aspects of contradictions, and they are tributaries. The contradiction between primary and secondary is to solve the problem, and we should grasp the key points. For example, if society wants to develop, it must focus on economic construction. When this contradiction is solved, social development will be solved.

There are sheep and wolves on the grass, because the main body is sheep. When sheep want to eat grass and there are no wolves around, eating grass is the main contradiction for sheep; 2. When wolves appear, running away becomes the main contradiction of sheep, and eating grass becomes the secondary contradiction.
