Han Yu has a famous saying that "study hard and play hard", which means that the depth of study lies in diligence and the waste lies in play.

Diligent and carefree, from Han Yu's "The Solution of Learning while Learning". It means that learning is proficient because of diligence, but it is abandoned in laughter. Things succeed because of repeated thinking, but they can also be destroyed casually. Throughout the ages, how many people have achieved their careers are all due to good work and laziness in play. There is a good allusion that says the same thing.

During the Warring States Period, Su Qin was ambitious at first, but because of his shallow knowledge, he was not reused in many places. Later, he made up his mind to study hard and sometimes read until late at night. He was really tired, and when he was about to take a nap, he stabbed himself in the thigh with an awl, bleeding profusely. He used this special method of "stabbing stocks" to drive away drowsiness, cheer up and keep on studying. He finally became a famous politician.

There is an ancient saying: "Dream without pains", which means that there is no free lunch and nothing will come. For example, learning depends on learning more, practicing more and thinking more, but if you just concentrate on playing, learning will go backwards, such as sailing against the current, if you don't advance, you will retreat.

And "industry is good at diligence, not enough to play" also shows that a deep industry foundation depends on diligence and hard work, and the results will definitely improve, while laughing all day will only accomplish nothing. For example, technical experts, it is by hard work and hard work against time that they have such profound technology today. On the other hand, if you don't study hard, you will neglect your studies and accomplish nothing.

"Everything you did was destroyed by thinking." In the following sentence, diligent study is the habit of loving thinking and exploring questions to find answers. Just like Edison, how did he succeed? How was the electric light invented? Don't you just rely on 1000 experiments and love to find problems? In addition, why didn't junior high school get into a key high school? Isn't it junior high school, when I was just playing all day and failed?

Therefore, we must remember: "Diligence and idleness ruin what we do." Take our study seriously and study technology hard, otherwise we will lose a lot.

Be serious and careless.
