The theme of "Happiness and Longevity" is the visualization of folk figures such as bats, deer, peaches and happy characters. People often use the bat's "bat" to express happiness "blessing"; Borrowing "deer" means "Lu"; Shoutao means "longevity", and the word "happiness" is used to express the yearning for happiness, wealth, longevity and celebration. "Happiness and longevity" is more common in jade cards in Ming and Qing dynasties, which may be related to the custom of being blessed with you.
