Interpretation: sticking to the rules and not conforming to the new fashion: pedantic theory, describing people as honest.
Usage:
Pedantic [chén fǔ]:] They are all adjectives, meaning "old-fashioned". "pedantic" refers to "people's words and deeds are old, rigid and out of date", which is mostly used in people's words and deeds and has a small scope of application.
"Outdated" means "abstract things such as ideas and concepts are out of date", which can be used not only for people's words and deeds, but also for things, and has a wide range of applications.
