I only know a little about couplets. For example: first, the door couplet is written vertically and pasted vertically; Second, reading couplets must go from right to left; Third, we must distinguish between the upper and lower parts. The upper part must be attached to the right hand side of the door, and the lower part must be attached to the left hand side of the door; Fourth, the method of distinguishing the upper and lower couplets In most door couplets, the last word of the upper couplet is flat, that is, the last word of the lower couplet is flat. Judging from these four articles, the word "peak" at the end of Sanqingshanmen couplet is flat, and the word "ground" at the end of couplet is flat, which should be wrong. On the other hand, for example, A Chinese Odyssey in the Blessed Land is the first part, and The First Fairy Peak in Hannan, Gao Lingyun is the second part. The blessed land is flat, the blessed land is flat, and the blessed land is flat. The blessed land and the blessed land are coordinated and the antithesis is neat.
