what is "happiness"? Many years ago, a little boy would say: happiness means playing games with friends forever; A migrant worker will say: happiness means that you can earn more money to support your family; A vagrant will say: Happiness is to live in a house where you have had your last meal ... Now? A 5-year-old child can already "play games all night"; Migrant workers no longer only pursue "it is good to have money", and people no longer just want to have a place to live, but turn their attention to villas and famous cars. This is not only a bad thing in a sense, but also reflects the development and progress of society. I didn't know what happiness is until I read Building a Happy China. Presumably, everyone knows the famous "father of hybrid rice" Yuan Longping! He has made positive contributions to our rice industry, which is not only the development achievement of China, but also makes the world sit up and take notice. What about his old man's house now In 28, Yuan Longping was pulled out of the water again. This time, it was not because of any scientific achievements, but because people broke the news that he went to the auto show with his wife. You may feel puzzled; How can an old man who is close to ancient times be attracted by the auto show? This may also show that people's living standards are steadily improving, and it also reflects the openness and modernization of society. What about his life now? After reading this article, I can have a word to describe it: simplicity. What can be seen from simplicity? Nowadays, post-8s and post-9s attach importance to fashion and modernity, and blindly pursue happiness. However, they never attach importance to simplicity and economy. They will say: Now is a time of peace, so what is the economy for? They are old people, they can stand it, eat less, and use less is fine! In fact, happiness is not only about not being praised and praised by others, but also about psychological feelings. Isn't it very happy to have a good meal at home with your parents? Everything around us is happiness. We should learn to cherish and cherish it, also for our motherland. Leonardo da Vinci has a famous saying: if you work hard for a day, you can have a good night's sleep; If you work hard all your life, you can sleep happily. Perhaps, only those thousands of farmers know the deepest! People often say that farmers have no quality, but have they ever known that the rice and vegetables that we need every day are all planted by their own hands! Have we ever known that their sweat soaked their clothes and they got only a small stack of rewards? Even so, they are still very happy because they have made contributions to the people. In fact, happiness is very simple. You don't need to cite a lot of figures to illustrate it. You just need to do what you should and live up to what you have done. Then, you will be happy. Only when you are happy can the country be happy, thinking that only a small piece of land and one person can be merged into a country. Happiness needs to be built by everyone. How should we, the new hope of the 21st century, build a happy China? First of all, we should study hard. Only by acquiring knowledge from teachers can we have real strength. Secondly, we should start from now on, protect the environment and take good care of flowers and trees, so as to form habits and cultivate our spiritual sentiment. In life, we should not only be as simple, hardworking and meticulous as the above two examples, but also be serious and not careless in doing things. Only by being a "Four Good Boys" and getting closer to our own strength can we build a happy China! Happiness is actually very simple.
