The Chinese character fu represents happiness and good fortune and is one of the most commonly used auspicious symbols in traditional Chinese culture. People usually write a large character fu on red paper, symbolizing the hope for family happiness, social stability, and national prosperity. Pasting the character fu during the Spring Festival is a long-standing folk custom. To celebrate the Spring Festival, every household pastes the character fu on their doors or walls, expressing their longing for a happy life and their expectation for a bright future. Sometimes, people paste the character fu upside down, indicating that happiness and good fortune have arrived.
