2. Form requirements: The most commonly used and original form of couplets is to stick between couplets (so it is also commonly known as couplets). The upper and lower couplets, together with the horizontal comments on the lintel, are the "doors".

This is because this four-character phrase is flat and easy to match, which makes the phonology harmonious and short and powerful. For example, "mighty spring breeze" means "flat and even". This is a flat set, and there are changes such as flat set and flat set. In addition, the phrase structure is easy to be uniform or uneven.
