Today I knew a new use for Czech adverbs, they can be used like adjectives. eg. Je mi smutně, Jdou mi špatně hodinky. But I am a little confused that: why use "mi" instead of "ja"? Shouldn't "ja" is a subject here? If I say, "květiny jsou krasně", is it correct? which form of the word "květiny" I should use? PS: I am a Chinese who is a beginner of Czech language, as the data for Czech language is too few in China or Chinese website, I have to seek for more data here. Thanks for anyone who answers this question, I am waiting for you guys' respond.
