Education is not to let people know what they didn't know before, but to urge them to put what they already know into practice. This can't help but remind me of a sermon, "Practice a thousand songs before you know your friends, and watch a thousand swords before you know your instruments", which comes from Liu Xie, a literary theorist in the Southern Dynasties. It means that only by mastering a lot of tunes can you understand music, and only by observing a lot of swords can you know how to identify a sword. It embodies the truth that practice produces true knowledge.
Yuan Longping —— Father of Hybrid Rice
Rice is the staple food of China people. But for a long time, the rice yield is not high and the population is large, so farmers can't meet the demand of "eating" by farming and planting rice all the year round. Yuan Longping, an agricultural scientist, is determined to tackle key problems for the country and solve this problem. Despite the poor working conditions at that time, he devoted himself to scientific research. In addition to teaching every day, it is to cultivate high-yield varieties in experimental fields. In his experiment, he found that the natural hybrid rice had big ears and full grains, and high yield, but when it was planted again the next year, it degenerated and lost its advantage. He wants to carry out an experiment to cultivate hybrid rice seeds that can maintain high yield. For this ideal, Yuan Longping spent a lot of energy, sometimes observing in the experimental field, even ignoring his own home. After 10 years of efforts, it was finally cultivated successfully.
Now, the yield per mu of this hybrid rice has reached more than 1 1,000 kg. After the nationwide promotion, the rice output in China increased by 1 000 billion kilograms in a few years, which is really a leap! Not only did it solve the problem of heat preservation in China, but it also went out of Tumen and went to the world to help some African countries increase food production. The United States and other countries also introduced his achievements. Yuan Longping is known as the father of hybrid rice.
? Calligraphers Wang Xizhi and Wang Xianzhi in Jin Dynasty
There was a great calligrapher named Wang Xizhi in the Jin Dynasty in China. According to legend, he studied calligraphy in Lanting Linchi, Shaoxing for twenty years. Because he often washes brushes and inkstones in the pool, the water in the pool is dyed black. Once, his son Wang Xianzhi asked him the secret of writing. He pointed to the eighteen water tanks at home and said, "You will know the secret of writing after you finish writing the water in these eighteen water tanks." Wang Xianzhi really finished writing Eighteen Tanks of Water and became a great calligrapher.
Students should not only learn theoretical knowledge, but also put theory into practice. I know it's not easy. For example, from reading to writing, you need to read thousands of books, and you need God's help to write. It is necessary to develop the good habit of reading more and accumulating more at ordinary times, and apply the accumulated reading knowledge to writing, so as to achieve the effect of "practicing thousands of songs and then knowing the sound, watching thousands of swords and then knowing the instrument".
