Xiaozhuang's 60th birthday was approaching, and he suddenly fell ill. Kangxi found that there was an ancient saying that "the emperor who succeeded to the throne" sought happiness and longevity, so he decided to seek happiness for his grandmother. After three days of bathing and fasting, Kangxi chose a brush engraved with the words "Fu Shu Ren" in block letters, wrote the word "Fu" on silk paper in one go, and decided to make an exception and stamp the seal of "Treasure of Kangxi's Imperial Pen"-the seal is a symbol of the emperor's power, which can only be stamped on imperial edicts and important official documents, and must not be stamped on ordinary calligraphy works. This word combines "blessing" with "longevity". The word "fu" means many children, many talents (wealth), many fields, many blessings and long life. Known as "the first blessing in the world." The tablet of Confucius is now hidden in Miyun Cave in Cui Jin Garden of Gongwangfu.
