Judo, Taekwondo, Karate, Aikido, Sanda, Free Fight and Wing Chun are suitable for girls to study.

Learn taekwondo. It is good for girls to practice this stovepipe to keep fit. If you learn Wing Chun, it will be more practical. But girls don't have to, because any actual martial arts will have certain requirements for strength and will definitely build muscles. It's good for girls to practice Taekwondo. After all, if they have tough will and temperament, they will be more beautiful!

If P.S. likes martial arts, it's fun to learn a routine. I also like martial arts fighting very much. I have practiced Taekwondo, Sanda, Sanda, Wing Chun, Brazilian Jiu Jitsu and China traditional martial arts, and I still know something about these aspects, believe me.
