Among them, we should pay attention to distinguish the upper and lower couplets of Spring Festival couplets. Generally speaking, there are four ways to distinguish:
1. Divided by hue. Spring Festival couplets pay more attention to leveling. The last word of the first couplet is flat, and the last word of the second couplet should be flat. 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).
2. Divided by causality. "Cause" is the upper part and "effect" is the lower part. For example, "urban and rural wealth is in the right direction, policy is wise, and food and clothing are plentiful", because only the "cause" of "urban and rural wealth" will have the "fruit" of "food and clothing".
3. In chronological order. Time is the first part and time is the second part. For example, "the wind sends Ying Ge to bid farewell to the old year, and the snow companions welcome Mei to welcome the new year", and "bid farewell to the old year" comes first and "welcome the new year" comes last.
4. according to the spatial scope. Generally speaking, the small one comes first and the big one comes last. For example, "managing the family diligently, uniting and building the country, making the country prosperous and the people safe." In this pair of Spring Festival couplets, "country" is bigger than "home", so "home" comes first and "country" comes last.
