‘Cháng mìng bǎi suì’ is a traditional Chinese blessing expressing the wish for someone to live a long, healthy life—specifically to reach one hundred years old. Literally, 长 (cháng) means 'long', 命 (mìng) means 'life' or 'destiny', 百 (bǎi) means 'one hundred', and 岁 (suì) means 'years of age'. Together, they form an idiomatic phrase that functions as a complete auspicious expression, not a literal description.

This phrase is commonly used during birthdays—especially milestone ones like the 60th, 70th, or 80th—and in Spring Festival greetings for elders. It appears on red envelopes, birthday cards, banners, and verbal well-wishes. Though it literally references 100 years, it symbolizes longevity, vitality, and good fortune rather than strict chronological accuracy. It carries deep cultural resonance rooted in Confucian respect for elders and Daoist ideals of harmonious, extended life.
