I am a small herder on the grassland. What mood is it? What is the law of the strength of four or two beats?

I am a small grassland herder, and my mood is to express the joy and pride of small grassland herders when grazing.

The law of strength of 42 beats is strong-weak-strong-weak. The beat takes a quarter note as a beat, and there are 2 beats in each bar. Most marches adopt this 2/4 beat form.
