Hualang Station is the name of a subway station in Seoul, South Korea. There are many colleges and universities nearby, such as the Army NCO School and Seoul Women's University. The elite trained here is called Hua Lang. In China, Hualang has three meanings: 1, "Brother Sharp" (beggar); 2, selling flowers lang; 3. When offering sacrifices, choose a beautiful childe, decorate it with Fu powder, and ride a flower horse called Hua Lang; Later, it was extended to South Korea, which is the third type. In ancient Korea, he was chosen as "Hua Lang". To become a flower lang generally needs to meet three conditions:

First of all, you need to be handsome. In fact, it is understandable that appearance worship has existed since ancient times;

Secondly, what is needed is aristocratic children. On the one hand, under the circumstances at that time, most aristocratic teenagers were literate and literate, and their knowledge level and cultural literacy were relatively high, so it was relatively easy to educate them. On the other hand, because the nobles in Silla often intervened in the political affairs, the rulers had to "start from the doll" if they wanted to instill the concept of kingship in them.

Third, absolute loyalty to the monarch is needed, which is also the fundamental reason for the establishment of the Hualang system.

In historical materials, Hualang people are known as "virtuous and loyal ministers, and since then good generals are brave and born in the son of heaven". After the Confucian culture advocated by the rulers of the Li Dynasty in Korea, the so-called "Flower Lang Spirit" has been circulating on the Korean Peninsula. With the emergence of politicians' political needs, trying to promote the patriotism of Korean nationals, the "Flower Lang Spirit" was naturally put on the stage as a sample. Park geun-hye's father, former South Korean President park chung-hee, who is famous for his iron fist, is also an advocate of Hualang spirit. There is an army in South Korea called Hualang Army, and the fourth grade of South Korea's Wu Xun Medal (Medal of Honor awarded to meritorious persons) is also called Hualang Wu Xun Medal. During his reign, Hua Lang became synonymous with martial arts and patriotism.
