I think it's good for a girl to be engaged in the dance industry for a long time. She must keep in good shape, and daily exercise is enough. If she thinks she's good enough, just sign up for the competition. In the future, you can go to a school or a training institution as a tutor, or if you feel that you have the ability, you can open your own dance studio and carry forward the dance. In the future, she can choreograph your favorite dance. The dance training industry is a long-term development industry, so don't worry about not having a job in the future.
