/kloc-It's a bit unrealistic to start practicing ballet at the age of 0/9, but yoga is easy to learn and can be divided into primary, intermediate and advanced. Therefore, beginners can practice from scratch, and there is no limit to where they practice. Moreover, yoga plays a great role in correcting people's body shape and posture. So I suggest you practice yoga. Of course, everything is difficult at the beginning, and persistence is the last word!
Or you can choose to practice physical fitness, just like many primary schools in Shenzhen have started to let students take physical fitness classes, so that they can maintain a good posture from an early age.
