Look at the last word of the couplet. The last word of the first couplet is three tones and four tones (even tones), and the last word of the second couplet is one tone and two tones (flat tones). For example, the last word is wàng Qiang, the last word is Xěng Xοng, and the last word is downlink.
Method 2: Meaning discrimination 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.
Method 3: Time relation discrimination method
It used to be the first couplet, but the new one is the second couplet. This is generally reflected in the Spring Festival couplets during the Spring Festival. Commonly used are zodiac rotation (dogs go/pigs come) and farewell to the old year/welcome to the new year.
Method 4: Range size discrimination method
Generally speaking, the small scope is the upper part and the large scope is the lower part, such as common words such as country, home, sea and lake.
Besides paying attention to couplets, time and couplets are learned.
There is a folk myth that Spring Festival couplets are immortals in the sky. When the Spring Festival couplets are torn, they will report to the Jade Emperor the situation of each household, hoping that the gods can bring good luck to the folk families. It is best to stick Spring Festival couplets between 6 am and noon 12 on New Year's Eve, tearing up the old ones, which means breaking bad luck and tearing up the old ones.
For example, posting money backwards means that the money has arrived. According to ancient rituals, it is synonymous with money, so posting money backwards means that money has been hollowed out. Folklore tells us that in ancient times, jars containing things, such as water tanks and wine tanks, were only labeled with the word "pour happiness", indicating that happiness cannot be poured, indicating that you are willing to be full. Like the door at home or in public places, you can't paste the word "Fu" upside down, otherwise it will pour it out.
