How to judge the grammatical errors of Chinese phrases? Some grammars are wrong, but they read smoothly, while others are correct, but they read clumsily.

Grammatical errors depend on the composition of sentences. We learned the subject-predicate-object complement in primary school, so we should know something about it. Common grammatical mistakes are, for example, this year, our province will comprehensively promote the issuance and application of residents' health cards, which can store the basic personal health information of urban and rural residents. This sentence should be exchanged between realizable and urban and rural residents, otherwise there will be grammatical problems, which is a sick sentence. As for the grammar that I can read, I don't need to say more.
