There remains a discrepancy not only between generality and particular, but also between particulars in the same generality, and further more between two particulars in different generalities. It is the universal degree of generality that influences the discrepancy of particulars in the generality. From this two points of inspiration can be drawn: 1) when dealing with matters with high universal degree of generality, we must pay attention to their peculiarities; 2) when dealing with matters with low universal degree of generality, we can be able to learn experiences and models from others. To this point, some people hold a partial or one-sided view.
