福寿 is a compound noun combining 福 (good fortune, blessing) and 寿 (longevity, long life). It's a traditional Chinese cultural concept that appears in auspicious greetings, decorative patterns, and ceremonial contexts — especially during birthdays, the Lunar New Year, or in blessings for elders. You'll often see it in the four-character phrase 福寿双全 ('may you have both good fortune and long life') or on gifts and artwork meant to convey best wishes for a prosperous and healthy old age.
