There are several ways to distinguish between uplink and downlink.
First, clear pronunciation and mellow voice, consistent sentences.
Second, the level and level are consistent and the tone is harmonious.
Third, parts of speech are relative and have the same position.
Fourth, the content is related, from top to bottom.
What I'm talking about here is how to distinguish by horizontal adjustment.
In most cases, it works every time.
1. the distinction between meaning and method: each couplet has its own specific meaning. When writing couplets, it is generally considered to be the bottom couplet with profound meaning, and the value of the top couplet is more of a guiding role. The upper and lower links are basically causal, because it is the upper link and the fruit is the lower link.
2. The distinction of time relationship: the old time is the first link in front, and the new time is the second link behind. This is generally reflected in the Spring Festival couplets during the Spring Festival. Commonly used are the zodiac and the old year/new year.
3. Range size: Generally speaking, the small range is the upper part and the large range is the lower part.
