Recently, one of Kim Yo Han's younger sisters won a gold medal at a national taekwondo competition for middle school students.
After the win, Kim Yo Han posted photos of himself with a cake with a congratulatory message on Instagram.

He has two younger sisters, who are currently taekwondo players.
As they are in the field where Kim Yo Han used to be, he is very supportive of them at all times.
Whenever his sisters win a medal at a national competition, he posts a post on his Instagram congratulating them.
The captions in his posts included, "You've done well! I'm so proud of you, my little one!", "You are so much better than I am! I don't have a medal from that competition myself. Congratulations!" and so on.

Previously, Kim Yo Han posted a photo of himself with his sisters, all wearing a taekwondo uniform.
Along with this photo, he even wrote, "My everything."
