There are almost 50 me outside and in the dormitory.

If there is a slight difference,

Because the air in the dormitory is not good,

Or have a lazy idea in bed,

I feel a little tired and want to lie down.

But you can't lie down when you do it on the ground.

Of course, doing push-ups on the grass with flowers and birds,

When you are tired, lie down and look at the blue sky.
