The society of our human beings is really a complex system.
Then what is the basis, or say, the smallest unit of such an unwieldy system? Usually family is considered to be the essential element of a society.
A main reason is that parents and children are linked because of their ties of blood.
This unique tie distinguishes it from any other interpersonal relationships. It grows for so many years without judgment, without limit. They love all the things belong to us, not only our strengths and gifts but also our weaknesses and faults.
You could also ask a mother about her rage if someone does her children harm.
I think it will be an unusual rage that we who don't have such experience can imagine.
Here, I just want to mention one point, that is, as the unique and special people in their children's lives, parents need to spend as much time as possible with their children.
By this, I don't mean that parents should spend twenty-four hours a day with children.
We often see and hear some moving things, for example, one mother saved her child desperately in an sudden accident, regardless of her own life.
This is what we called great love of mother, I think.
