I subscribed the channel and watched Jonsu's episodes. According to an old TV schedule
, Jonsu's episodes were originally aired in October 2012, so they were probably filmed in summer 2012. The episodes contain mainly riding instructions, but here's a summary of what Jonsu said about her own experience with horses:
Jonsu became "horse mad" when she was seven years old and had a summer break from school. She was thinking about horses all the time and draw pictures of them. She had her first riding experience when she was four or five years old. Then she rode on a pony that was led by an instructor. When she was seven, riding became her hobby and she learned to control the horse herself. She says that experience with horses has taught her to respect animals and nature. It has also taught her to take a contact to an animal and understand animals' behaviour.
