What are the ways to write and paste couplets? Please ask pedestrians and non-pedestrians for directions.

In writing, we should mainly use regular script, official script and seal script. It is suggested to write regular script in the traditional way. Of course, simplification is also possible, but don't mix the complicated with the simplified.

Stick it up, facing the gate, the right hand is the upper half, the left hand is the lower half, and the horizontal batch is from right to left. But now there are also right-hand men, and the couplets given by insurance companies and printed outside are common.

In addition, the number of words is equal, so I won't say much about the basic knowledge of these couplets.
