"Wealth comes from all directions" should be posted on the right hand side (that is, the left side of the door), and "Four directions enter the treasure to welcome the god of wealth" should be posted on the left hand side (that is, the right side of the door), and the horizontal batch should also be read from right to left. Upper and lower couplets cannot be posted backwards.

Spring Festival couplets are divided into upper couplets and lower couplets. It is not easy to distinguish the meaning of upper and lower couplets. Generally speaking, the first word of the first couplet is "Xu", which is three or four tones, and the first word of the second couplet is "Ping", which is one or two tones. According to this law, we can accurately distinguish the upper and lower couplets.

Couplet form:

As the name implies, couplets should be "paired", that is, they are composed of upper and lower couplets. The number of words in the upper and lower couplets must be equal and the content should be consistent, that is, the upper and lower couplets can be "linked" (parallel), and two unrelated sentences can not be combined together to form a couplet. Generally, couplets are written vertically, with the last word (tone) of the first couplet posted on the right (hand) and the last word (tone) of the second couplet posted on the left (hand).
