When expressing approval or recognition of something, people often say ok, which means "good", "not bad" and "not bad". This term was originally used by American railway switchmen.
When on duty, if everything is normal on the railway, say Allcorrect, that is, "completely normal". Because the All sound is close to "0" and the correct sound is close to "K", for convenience, workers omit reading "OK" to mean the same thing. Later, the meaning of the word evolved continuously, and now it not only refers to "good", "good" and "not bad", but also includes the meaning of agreeing with and acknowledging other people's opinions. It is also used for signing, expressing agreement and approval.
