According to historical records, in the fifty years of Qing Qianlong (1785), Emperor Qianlong wrote a "longevity" for more than 3, long-lived old people at a "thousand-banquet". The word "shou" is round and full, with smooth and steady strokes, such as flowing water, smooth and natural in one go. The word "longevity" written by Gan Long with his love has created a miracle in the calligraphy world intentionally or unintentionally. Under the fine quality, it really has the taste of a masterpiece. The word "longevity" can be broken down into two auspicious words: "life is safe" and "immortality". Its ingenious conception is really a stroke of genius. The word "shou" shows amazing imagination in the creation and application of fonts, and it not only creates variants, but also arranges and combines them skillfully. Moreover, it is not a simple arrangement and combination, but a complex combination form to express the hope for longevity and peace, which not only has profound connotation, but also is a beautiful work of art. Because it comes from the hands of the son of heaven, it is known as "the first life in the world."
