How do 9 people line up to sing?

When nine people sing, they can change different formations. Let's talk about how nine people line up to sing.

0 1 Four people can stand in the front row and five people can stand in the back row. Four people in the front row are shorter, and five people in the back arrange taller people, which looks more comfortable.

You can also arrange nine people in an arc, with tall people standing in the middle and short people standing on both sides, so that you can show the whole picture of everyone.

You can also have three people in the front row and six people in the back row. The three people in the front row stand in a straight line and the six people in the back row stand in an arc. The back row stands tall and the front row stands short.

You can also stand two shortest people in the front row, three people of medium height in the second row and four people with the highest figure in the third row, so that everyone's head can be exposed, just like the arrangement of bowling sticks, which looks neat.
