Nowadays, korean culture is wide spread among the Asia. In China, a lot of teenagers like the culture of Korea, especially their and drama. I want to express my opinion towards this phenomenon.
I think somehow this is nonsense. In my opinion, the Korean groups become popular because mainly they are good-looking, instead of really appreciating their music or their talent. In fact, compared to the groups in Taiwan, mainland China and even overseas, the groups and singers are definitely much better than that of Korea. Just because their idol are good-looking (some may only due to plastic surgery), the teens may copy their idols and do plastic surgery as well! This may create a big problem among the society as teenagers may justify others from their appearance only but not their inner heart. Music is actually a great gift given by God. But in my point of views, some Korean so-called "Singers" and "Superstars" are ruining the gift. Music from them is no longer an elegant rhythm but a sign of the popular thing in some places and mostly they have strong beats and rhythms that don't bring out the beauty of music.
Moreover, the Korean drama is also causing problems among the society around the world. The influences brought by it is so large that some teens may copy their idol's behavior in the drama. They may also spend lots of time watching these non-educational drama, which cause them a drop in their academic results. More serious is that people, especially students may spend lots of money just in buying related goods in order to "support" their idols. But most of all are using their parents' money! Is that what students nowadays should focus on? Of course not.
Even though it does affect teenagers nowadays, we couldn't do many things to help with this problem. Just because it's their freedom to choose their idols! But we could do is to educate the teenagers to build up and develop a correct moral values.
