How to write the movie script "Fighting"?

What you want to write is a movie script, you don't need to write shots, you can write important key pictures that reflect the characteristics of the characters, but if you want to shoot, don't worry, you can write down your requirements for action and leave the rest to martial arts instructors and film directors. You don't have to gild the lily by writing how they fight and what they do. It's none of your business.

I once saw a big screenwriter write only one sentence in the fighting scene: they fought. (I pour! )
