China's ancient philosophical story, the historical story of Zheng people making umbrellas and crossing national rice, take history as a mirror, take history as a mirror. This inspiring story is full of profound practical significance. In a remote place in Zheng, there was a man who didn't know what to do all day. He did many things without success, so he wanted to learn a technology. One day, he heard that making umbrellas was very good, so he learned to make umbrellas from others. He learned quickly and went home to make his own umbrella after learning. But unfortunately, it caught up with the drought for three consecutive years, and the land was almost smoking. It didn't rain at all, and his umbrella was useless. So he gave up making umbrellas and learned how to draw water from a well instead. When he successfully learned the tools to draw water from the well, it rained heavily for three consecutive years, and all the tools he made were useless. The man thought for a long time, decided to make an umbrella, and later switched to an umbrella. When he made a large number of umbrellas to sell in the street, soon, Zheng's robbers were everywhere, and wars and disputes broke out. People wear military uniforms to fight, and few people use umbrellas, so he wants to make weapons again, but at this time he is too old to make weapons. In Yue State, there was a man who was good at farming. It is said that all kinds of fruits and vegetables he grows are very popular. But he is not satisfied with just planting these. He wanted to grow some food, because food was very scarce, valuable and precious at that time, so he decided to give it a try. But there is a big difference between growing food and growing vegetables. He has never been exposed to growing food, so he was advised not to give up what he is good at and engage in growing food that he has never been engaged in. If he looks bad, he will delay everything. Is it not worth the loss? He sounds reasonable, but he believes that he can make a difference in growing food, so he is determined to grow rice regardless of other people's dissuasion and opposition. He also believes that no matter what happens, his determination to grow rice will never change, even if the weather conditions are complicated and changeable, or the market for vegetables and food keeps changing, he will insist on growing rice well. On this day, he found a barren hill and slope, called many people to help, cleared a field and planted rice. Because he is very proficient in planting, coupled with serious study, the rice he planted is obviously harvested, and it is harvested every year. But at this time, it was catching up with the once-in-three-year flood, and someone advised him to release the water from the ground to grow millet. He didn't take the man's advice, but continued to grow his own rice. Before long, the weather became drier year by year. The man calculated his own harvest, and as a result, he not only withstood the poor harvest in previous years, but also made a considerable surplus. Everyone saw that he insisted on his decision so persistently, and sure enough, he finally got a good return, and everyone felt very admired. They began to learn the skills of growing rice from him. The man didn't refuse everyone's request, but explained how to grow rice to the blood man in detail. Finally, he didn't forget to tell everyone: "No matter how the weather changes, you can't give up halfway!" Everyone nodded and said yes. In philosophy, Zheng began to learn to make umbrellas. Because of the dry weather, he learned to draw water from the well instead. Later, when the weather was waterlogged, he made an umbrella instead. As a result, there was a war and no one bought his umbrella. When he wanted to switch to weapons again, he was powerless. On the other hand, Vietnamese people decided to grow rice. No matter how others dissuade them and how the weather changes, they consistently stick to their own practices, and the result is of course fruitful. You must persevere in doing things, and you can't change your mind just because of setbacks or difficulties. Only by persisting in doing one thing and striving to overcome all kinds of difficulties and dangers that may be encountered can we finally achieve our goal. If you are full of enthusiasm and are not single-minded, you will eventually lose your reputation and accomplish nothing.
