As the most important traditional festival in China, the Spring Festival is celebrated in the most solemn way. However, in recent years, something has been changing. Twenty years ago, my main impression of the Spring Festival was made of four things: the reunion dinner, new clothes, fireworks, and the CCTV Spring Festival Gala. Half a month before the Lunar New Year, my parents were already purchasing New Year goods, including candies, wine, and meat. In particular, every family member got a new outfit. On New Year's Eve, relatives around the world would come back home. Table was piled up with pork, lamb, beef and fish, which were rare in everyday life. Dishes could be more than a dozen. After dinner, people all over the country would watch the same TV program, the CCTV Spring Festival Gala. At midnight, when the clock's hand hit 12, gorgeous firework would resound across the sky. Changes are obvious. In the past few years, food, clothes and entertainment during the Spring Festival are no longer special. It is because the world has undergone rapid changes in the past two decades, even faster than the past few centuries. The economy is booming. We are no longer worrying about food and clothes. People have begun to pursue healthier eating habits. For clothes, warmth is no longer the most important criteria. We are more inclined to buy clothes at the beginning of the season. We'd like to follow the trend of fashion. The fireworks are indeed gorgeous and wonderful. But for sustainable development of the global environment, we also stop setting off fireworks in most urban areas.
