The Chinese character "fu" (福), which signifies happiness and good fortune, is one of the most prevalent auspicious symbols in traditional Chinese culture. It is traditionally written in large calligraphy on red paper, symbolizing hopes for family happiness, social stability, and national prosperity. Posting the "fu" character is a long-standing tradition during the Spring Festival. As part of the celebrations, households paste the "fu" on their doors or walls to express their aspirations for a happy life and a better future. A common custom is to hang the character upside down. This practice plays on a pun, as the word for "upside-down" (倒, dào) sounds like the word for "to arrive" (到, dào). Thus, an inverted "fu" represents the "arrival" of happiness and good luck.
