关于……

关于…… introduces the topic being discussed: “about / regarding....” It can appear before a noun phrase or at the beginning of a sentence to set the topic. Use it when the sentence really needs this meaning, not just because the English/Vietnamese translation seems close. Pay attention to position: the phrase introduced by 关于 usually comes before the main statement or directly before the part it modifies. Common mistakes are using it as a verb, placing it after the result, or confusing it with a similar connector such as 因为, 关于, 根据, 按照, or 对于.
