I want to write my own couplets, but I heard from bricklayers that couplets are exquisite. What is exquisite (geomantic exquisite)?

As far as I know, exquisite couplets should refer to shrines or shrines and anything else can be written casually, as long as it is not too out of line and meets the basic requirements of couplets.

It is said that the couplets of Shentai should follow the law of reincarnation of the ecliptic. Generally, it is written according to Xiao Huang Dao, and the last word of every sentence should fall on the word "fate".

In addition to writing couplets on the altar, some places can also write couplets on the beams when they are capped, and this couplet should also follow the law of reincarnation of the ecliptic.

It is suggested that it is better to do as the Romans do, not to be unique and unconventional, so as not to attract people's discussion.
