"Echt" 和 "Ehrlich?" 和 "Wirklich?" 的差別在哪裡？如果不好說明，請提供一些例句。

Technically they can be used interchangeably to mean "really" to emphasize an adjextive or adverb, although I'd say "ehrlich" would be the least common word to be used in that way, people usually use "echt" or "wirklich" to mean really. "ehrlich" used as an adjective means honest, "echt" used as an adjective means real and "wirklich" is usually always used to mean "really", i don't even think it's a proper adjective haha
But saying something like "Er rennt echt/wirklich schnell" (He runs really fast) sounds really natural in both cases, "ehrlich" would maybe rather be used in a situation where someone is not believing something you have said so you say that it really (for real) happened that way, but you could just use "echt" or "wirklich" in those cases as well, so whenever you want to translate "really" into german, " echt" or "wirklich" are the best way to go
