有一次我在问我自己,PS 到底是啥意思啊。。。我都都用习惯了。。
post scriptum
If you are talking about P.S. when used in writing, it stands for postscript
, from the Latin post scriptum, meaning "written after." It is generally
used in letter-writing to indicate something added after the body of the
letter was completed and signed.Sep 20, 2018
