Life is a process, in which we have experienced the joys and sorrows of life, and at the same time we have seen the changes of society. Individual social people and traces will become the witness of society and history through the passage of time. I was born in 1970s. After 30 years of reform and opening up, I witnessed and appreciated the great and gratifying changes that have taken place in China in the past 30 years. At the beginning of reform, I was still young. I am a rural child. At that time, everyone was poor, so it would be nice to have a meal. I remember one year I ate a cake made of elm money. I can't talk about wearing them Most people's pants are still patched. The clothes I wear are all changed by my brothers and sisters above. I wear them one by one. When it was my turn, I was really embarrassed. My pants were gone. Fortunately, I am young and don't mind much. Not to mention shoes, it's normal to run around barefoot. Although life is hard, I heard from my parents that it was even harder at that time. Food stamps are needed for eating, and cloth tickets are needed for buying cloth, not to mention having no money and having no place to buy it. The so-called "the whole family wears a pair of pants" has become a joke of the younger generation. Up to now, who has a good relationship with whom is also a metaphor of "wearing a pair of pants". Parents are witnesses of their times. When I was in primary school, I ate normally and occasionally bought some new clothes. In middle school, I took the lead in replacing the hand-made cotton-padded jacket, putting on a down jacket and having a pair of "big-headed leather shoes", which was very fashionable at that time. Later, the students put on down jackets in twos and threes. When I was in college, I could order a snack or something to improve my life when I was eating in the school cafeteria. Many students have begun to pay attention to the material, style and brand of clothing. At work, everyone has been talking about diet and nutrition, clothing taste, and making plans for "tickets, houses and cars". A few years later, some of my classmates and friends started running. I don't have a car, but I am in front of them. That's because I have environmental awareness! I tell you, I am not short of money. After the material life is rich, people are increasingly pursuing spiritual life. Be a volunteer and build a volunteer team. In short, everyone is duty-bound as long as the motherland needs it. At the same time, the progress of science and technology has brought the network world. The network has expanded our knowledge with its convenient and fast advantages. People share resources here and have no distance from the outside world. Over the past 30 years, personal life has changed a lot, and there have been many national events. Hong Kong returned to China in 1997 and Macao returned to China in 1999. 1998 catastrophic flood disaster in southern history; Successfully defeated SARS in 2003; In 2008, the Olympic Games was successfully held and Shenzhou VII was launched. Astronauts also walked out of the cabin, but unfortunately they also suffered from ice and snow disasters and Sichuan earthquake. However, no matter what difficulties they encounter, the people of China show that the Chinese nation is a great nation with their indestructible will and strong cohesion. In the past 30 years, China has risen from twists and turns, and the spring breeze of reform and opening-up policy has made it glow with amazing vitality, and the whole Chinese nation has moved towards great rejuvenation.
