Parents influence children's concept of mate selection. What a person's mother or father looks like, then he chooses the type of wife and husband, just like his parents. This is what people usually call the prototype of family origin. The personality and living habits of family members will affect children's mate selection criteria. Therefore, after Song Hye Kyo Jing became Song Joong Ki's wife, a series of behaviors and habits may also become a problem for Song Joong Ki's father to think about, so that his daughter-in-law has a place in his heart.

In addition, it is said that Song Hye Kyo Jing has never given birth to a child, which will certainly bring resentment to Song Joong Ki's father. Because South Korea is originally a society with the traditional concept of giving preference to boys, and it is more important for Koreans to carry on the family line, Song Joong Ki's father must also have contradictions with Song Hye Kyo in this respect.
