What does the last sentence of the third letter in "Fu Lei's Family Letter" mean?

1. The first letter:

Fu Lei’s deep love for his son can be seen between the lines. For my son who has grown up, I hope that he will thrive and develop outwards, but I cannot bear to let my child stay away from me. In fact, parents are like this. From pregnancy in eight months to delivery in October, parents work hard to nurture their children step by step, in order to hope that their children will be useful and will not live on the streets in the future.

However, when children become talented, it is also the time to leave the roof and fly alone. As a parent, I am both happy and sad for them. After all, it is a matter of flesh and blood. As we should appreciate and understand the painstaking efforts of our parents, let them see what they want to see - our happy life, which can be regarded as repaying our parents for their hard work in raising us.

2. The second letter:

It includes Teacher Fu’s recording of his son, detailed analysis, and objective appreciation. And later he mentioned his hope for his son. This is the way parents educate their children.

You must not only show your affirmation of your children, but also give them the determination to work hard and the confidence to succeed. On the other hand, they also put forward their own hopes and pointed out the way forward and the direction of development for the children. As children, we should also learn from our parents' experiences on the path guided by our parents, and learn from each other's strengths to develop our own new path.

3. The third letter:

As a parent, my son has mixed feelings about how to deal with the ever-changing society. Use your own experience to remind your son to take the road of resentment less and take more shortcuts. This is what parents all over the world think. Children are the continuation of parents’ lives and the hope that holds up the sun in their hearts. Parents take detours and do not want their children to repeat the same mistakes. They hope that they can "go to a higher level" than themselves.

As adolescents, we should let go of our rebellious mentality, listen to our parents’ lessons, and understand their parents’ painstaking efforts. In fact, this is also for our own good and for our future life to be easier and happier.

4. The fourth letter:

The mother is attentive, the father has good intentions for his son's future, and the mother is concerned with the most subtle things - his son's emotional issues, Give your son a clear direction. Tell him how to deal with his emotional and career issues, and let his son understand the key points.

We should also accept the lessons from Fu Lei’s wife. We should understand our priorities, our tasks, our path and direction, know what we should and should not do, and grasp the direction. This helps us succeed.

5. The fifth letter:

Father Fu Lei blamed himself for being strict in disciplining his son and using "cruel" methods. It turned out to be my own mistake. Hey, actually this is the deep love for one’s son! "If you don't work hard when you are young, you will be sad!" When his son was young, Teacher Fu Lei was strict and meticulous in discipline and "cruelly abused" his son Fu Cong.

It sounds like a joke, where is the father who abuses his own flesh and blood? As the saying goes, a filial son will come out of a stick, but what Teacher Fu Lei said is that a wise man will come out of a strict father.

Normally, when our parents engage in "violence" against us, we should have an understanding attitude, and we should be considerate of our parents' anxiousness. Because they are doing this to be kind to us, but they also hate that iron cannot be transformed into steel. After all, parents all have the hope that their children will become successful and their daughters will become successful
