The edge of a sword comes from sharpening, and the fragrance of plum blossoms comes from the bitter cold

This is a famous saying.

There are several opinions on the source (or author):

①Ancient sayings, or proverbs or sayings, are not written by any famous person.

②Lu You

③Zhu Xi

④Du Fu

⑤Mao Zedong

⑥Chen Yi

< p>I checked the electronic search version of "Complete Poems of the Tang Dynasty", the electronic search version of "Complete Song Ci", the electronic search version of "Sikuquanshu", and the electronic search version of "Sibu Series", and determined that these two sentences did not exist among the ancient poets. I also looked up the poems and articles of Mao Zedong and Chen Yi (incomplete), and searched on the Internet. It is basically certain that it was not written by Mao or Chen. Therefore, I can basically be sure that it is a common saying and not written by a certain person.

From the Diligent Chapter of "Warning to the World".
