The beginning of "life is easy to get old, but not easy to get old" is abrupt and magnificent. "Life is easy to get old" means that personality is universal, youth is fleeting and life is short. Only when it is fleeting, we should strive to make progress and make contributions, and don't let the new year's goods pay off. "It's hard to get old" is to personify the universe. Winter goes and summer comes, and works at sunrise and rests at sunset. Spring and autumn are more orderly and the situation is always new. But "difficult to get old" is not "not old" because "metabolism is a universal and irresistible law in the universe". "Life is easy to get old" and "life is difficult to get old", one is endless; One is short and the other is long; A rapid change, a slow change. There are similarities and differences, differences and similarities, opposites and unity. This is not a simple attachment to the old adage "Heaven is the key, and a gentleman strives for self-improvement", but a clear and profound understanding of life in the universe, which reveals the true meaning and eternal truth of life, shines with the brilliance of dialectical materialism and has a strong aesthetic enlightenment significance. "Double Ninth Festival" comes from the first sentence, which is not only a further extension of "it is difficult to get old", but also a timely statement, which leads to: "Double Ninth Festival today, the yellow flowers in the battlefield are particularly fragrant." Today's Double Ninth Festival is a progressive repetition of the annual Double Ninth Festival. It seems the same, but it's actually changing and different: it's a festive season, and this place has a unique scenery.
