Today, The original Five Codes of Human Conduct have been correlated into the so-called Eleven Commandments of modern day Taekwondo, which are:
Loyalty to your country Respect your parents
Faithfulness to your spouse Loyalty to your friends
During the Silla dynasty (A.D. 668 to A.D. 935) Taek Kyon was mostly used as a sport and recreational activity. Taek Kyon's name was changed to Subak and the focus of the art was changed during the Koryo dynasty (A.D. 935 to A.D. 1392). When King Uijong was on the throne from 1147 through 1170, he changed Subak from a system that promotes fitness to primarily a fighting art.

Belt color epxlanation
The explanation of belt colors was derived from the book of General Choi Hong Hi.
In WTF Taekwondo there are 10 Geups, starting from the 10th Geup (white belt) and ends with the 1st Geup (red-black belt). The term "Geup" means degree. The term "Dan" means phase. There are 9 Dan degrees, starting with the first and ending with the 9th. All Dan-degrees are represented by a black belt.
White Belt (10th Geup)
The color white indicates that a person is "innocent", has no knowledge of Taekwondo. The white-belt is automatically gained by taking Taekwondo classes.
Yellow Belt (8th Geup)
The color yellow indicates that the person is getting to know the basic techniques, this stadium is compared to a plant growing its roots.
The student going for yellow-belt is usually not skilled enough to show "Chayu daeryon" (non-contact sparring). Instead the student has to show "Sajoe" ("four-direction-movement", one specific technique shown to all directions).
Green Belt (6th Geup)
The color green indicates that a student is growing as a Taekwondo student. The color of the belt is compared to a plant growing its leafs.
Blue Belt (4th Geup)
The color blue indicates that a student is reaching higher, like a plant that is growing towards the sky.
Red Belt (2nd Geup)
The color red indicates danger. The student is warned to practice the control of his/her movements. The color red also warns an opponent.
W.T.F. Taekwondo requires that one has to be 16 years old to get a black belt. If younger, you get a Poom, which can be replaced by a black-belt when passed the age of 16. The requirements are the same as for the black-belt.
Black Belt (1st dan)
Black is the opposite of white and means the maturity of the student in the art. It also is an indication of being impenetrable for fear and darkness.
