Wan Li frost in the vast river. "Not like spring. Better than spring, it is the Wan Li frost in the vast river. " Excerpted from Mulberry Picking and Double Ninth Festival by President Mao Zedong. The original text is: life is easy to get old, but it is not easy to get old. Today is Chongyang, and the yellow flowers in the battlefield are particularly fragrant. The annual autumn wind is not as strong as spring. Better than spring, just like Wan Li frost on the vast river. This word was first published in People's Literature in May of 1962. The work begins with a philosophical aphorism, "Life is easy to get old, but not easy to get old", which is abrupt and magnificent. "Life is easy to get old" is to universalize personality and make life short. Only when it is fleeting, should we strive to make progress and make contributions, so as not to let the years pay off. "It's hard to get old" is to personify the universe. Cold comes and summer goes, sunrise and sunset, and spring goes to Qiu Lai, and the scenery is always new. But "difficult to get old" is not "not old" because "metabolism is a universal and irresistible law in the universe" (Mao Zedong's On Contradiction). And "the poet's life in the universe must be both internal and external." Enter it so that you can write; Beyond it, we can observe it "(Wang Guowei's Words on Earth). "Life is easy to get old" and "life is difficult to get old", one is endless; Short for a while, long for a while; One changes quickly and the other changes slowly; There are similarities and differences, differences and similarities, opposites and unity. This is not the simple trend of the old adage "Heaven is healthy, and a gentleman strives for self-improvement" (Zhou Yigan), but based on a profound understanding of cosmic life, it reveals the essence and eternal truth of life, shines with the brilliance of dialectical materialism, and has strong aesthetic enlightenment significance. "Double Ninth Festival" comes from the first sentence, which is not only a further extension of "Heaven is hard to get old", but also a universal category that appears in cases. It is timely and timely, and points out the purpose, resulting in the following: "Now, the yellow flowers in the battlefield are particularly fragrant."
