There are two ways to distinguish the upper and lower couplets: flat, flat in Spring Festival couplets, flat in the last part of the couplet, and flat in the last part of the couplet.
For example, "Qian Shan laughs at spring" ("laughter" is a derogatory term) and "happiness is enjoyed by everyone in the world" ("happiness" is a flat voice). Therefore, the future of generations of Fumen is good.
Couplets, also known as couplets, are also known as dual plays, door pairs, spring stickers, spring couplets, couplets and so on. Is it written on paper, cloth or engraved on bamboo, wood and columns?
