My wife is 'the Minister of Economy' of my family.

In my father’s generation, they experience Korean war in 1950. The People were poor. Their life is full of pain. They thought “Even though I am poor but my children should not be”. So, the men worked hard for money and the women saved and spend money for their children’s education. I think, from then, the wives have the power of family’s economy. (It is just personal opinion) For a better future, it is worth the sacrifice.
