The five concepts of "Fu Lu Shou Xi Cai" are widely used in various occasions in China traditional culture. The first couplet: Fu Man's door is warm in spring. This couplet describes that the blessing is full of doors, and the warm breath of spring comes with it.
The second couplet: Luying Courtyard is good for Qiu Guang. This couplet echoes the first couplet and describes that the courtyard is full of Luwei and beautiful Qiu Guang. Horizontal criticism: good luck is a summary of the upper and lower couplets, and also a summary of the theme of the whole couplet.
