The attributes of national natural science issues require: encourage exploration and highlight originality; focus on frontiers and find unique approaches; demand-driven and cross-integration.

1. Encourage exploration and highlight originality.

If you choose "Encourage exploration and highlight originality", you have to consider the nature of the application and the scientific problem. It must be written from the perspective of "whether it is original and worth encouraging to try", and focus on the innovative points ( New ideas, new theories, new methods, new technologies, etc.) elaborate on the reasons for judgment. Innovation is also divided into different levels: very good, good, average, poor and so on. Note: How and what the judges evaluate should be written according to the requirements!

2. Focus on the frontier and find new ways.

Since you have chosen to “focus on the frontier and find an original approach”, you have to consider the nature of the application and the scientific problem. It must be written from the perspective of “whether it is novel and original.” Originality is also divided into different levels: very good, good, average, poor and so on. Note: Focus on originality, not originality!

3. Demand traction and cross-integration.

If you choose "demand traction and cross-fertilization", you must consider the nature of the application and the scientific problem. It must be written from the perspective of "whether it is oriented to national needs and trying to solve the basic problems behind technical bottlenecks." We must also understand that this is the characteristic of "interdisciplinary".

It can be seen that when choosing different scientific problem attributes, you have to consider how the NSFC evaluates such projects and which aspects to elaborate on. You cannot do it arbitrarily!
