Son, sometimes you ask, why do you have to learn so much? Dad doesn't want to lecture you, or you have seen a short period of seven years' life, in which the child who didn't study hard became a tramp in middle age, although his family was not bad. Dad doesn't want to tell you your ideal, although you say you want to grow up to be a scientist and explore the unknown universe. After all, these things are still a little far away from you, because in ten years, you will have to face the choice of the college entrance examination. Recently, we upgraded all the plants to level 4, and we played the Kung Fu world together again. We found that it was extremely difficult for the bronze man to pass, and the bronze man was killed immediately before his resurrection, which became super simple. Why is this? Because your plants have become stronger.

Remember the days when we had to pass the Tongren checkpoint with 2-3 tactical cucumbers? It was a terrible experience. Powerful zombies almost make us want to give up and even turn to external forces. Those external forces are tactical cucumbers, or it may be your father and me. I'll do my best to help you through the difficulties in the end. This is too much like our life. When we study every day, we may encounter many problems. Those difficult knowledge, like powerful zombies, keep trying to eat your plants and beat you because you are not strong enough. Dad lets you punch in every day, and you make progress every day, just like unconsciously, your world is full of all kinds of powerful plants, and with the deepening of learning, these plants are getting more and more powerful. When your plant is strong enough, you can look at the topics that torment you and make you feel difficult to learn. Has the topic become simple? No, your ability has become stronger. The topics are still those topics, just like the level in Plants vs Zombies. The difficulty hasn't changed, but you have become stronger, so the difficulty is simple.

You often ask why you have to learn so much. There are more than 100 plants in Plants vs Zombies, and each plant has its own function. Some plants help you light up the road ahead, some plants help you get sunlight, some plants help you water the fire extinguisher, and some plants prevent other plants from being swallowed up by black holes. If you lack some plants, you will find that some checkpoints will become difficult. You may say that you don't need more plants than 100 to get through customs, but does more plants give you more possibilities and make your life more exciting? Dad asked you to learn a lot of things, not because this knowledge will definitely play a leading role in your future life, such as learning English, learning Spanish, learning Japanese, reciting Tang poems, learning graphic mathematics, and Khan Academy, which are all needed at a certain stage of your life, and also add more possibilities for your future. Just as a plant can't defeat zombies, richer plants and more varied knowledge can help you cope with more complex challenges.

Children, let you learn more, not for your father's own sake, but for the sake of other mountains that look short in the sky. When you climb to the top of the mountain, for the pleasure of stepping on difficulties one by one, and to despise the powerful ability of the enemy when you are strong. Father wants you to learn, and I hope your life will get smoother and smoother! You are going to primary school soon, Jiayou, come on!

Love, dad.
