I practiced Taekwondo to the purple belt. Why do my classmates laugh at me for not having a purple ribbon at all?

10 is leucorrhea: it means blank, with no knowledge of Taekwondo at all, indicating the entry stage.

Grade 9 is yellow and white.

Grade 8 is the yellow belt: it means the earth, the vegetation takes root and sprouts, and it means the basic stage of learning.

Level 7 is yellow with green stripes.

Grade 6 is green belt: it means vegetation, growing green vegetation and indicating the stage of technological progress.

The fifth level is green belt and blue bar.

The fourth level is the blue belt: it means the blue sky, and the vegetation grows vigorously towards the blue sky, indicating that the progress has reached a quite high stage.

The third level is blue ribbon and red stripe.

Level 2 is a red belt: it means danger, has considerable strength, shows self-denial, and warns opponents not to approach.

1 is a red belt and a black bar.

Black belt: indicates the opposition of white. Compared with white technology, I have mastered it, that is to say, I can also exert my ability in the dark.
