    Soap operas from South Korea have been popular in China for more than twenty years now. So it is not the first time for the soap operas made in China to feel less popular. But this time, they are facing more difficulties, for The Heirs(继承者们)and My Love From the Star really made a full success.

    A senior official said he sometimes watched soap operas from South Korea, as well as House of Cards, an American opera about politics（政治）. These operas made both in South Korea and in America have a lot of lovers in China.

Many people agree that China's soap operas can't be much loved by most Chinese, because they are not as interesting and exciting as those operas from South Korea and America, such as My Love From the Star, a South Korean love story between a time-traveling professor and a famous movie star.

    However, South Korea not only provides soap operas but also some variety shows(综艺节目). Where Are We Going, Dad? is not an original Chinese show. We learned it from South Korea although not many in China know about that fact.

    South Korea has created many popular shows and these stories tell there's no difference between men and women but in their country men are certain to play a more important role.
