I am a dance teacher. Learning ballet will make children's figure lines grow well and have temperament. The training of soft opening is actually helpful to the growth and development of children. Usually they will grow taller, and there will be no such situation as you said. Children who learn amateur ballet will not have too obvious external characters, and some children have almost no external characters. Soft-open training is not directly related to the outer eight characters, but only when training the feet. If you think your child learns ballet because she is afraid of being ugly, you can learn folk dance, or attend the China Dance Grading Training Course.
