至于

The Chinese word 至于 (zhìyú) is composed of two characters: 至 (zhì) and 于 (yú). 至 means "to arrive at" or "to reach", while 于 is a preposition that can mean "to", "at", or "until". Together, 至 and 于 form the word 至于, which means "as for", "with regard to", or "concerning".至于 is often used to introduce a new topic or to provide more information about something that has already been mentioned. For example, in the sentence 至于他的工作, 他很努力 (zhìyú tā de gōngzuò, tā hěn nǔlì), the phrase 至于他的工作 (zhìyú tā de gōngzuò) means "as for his work". The rest of the sentence, 他很努力 (tā hěn nǔlì), means "he works very hard". So, the whole sentence means "As for his work, he works very hard".至于 can also be used to express a purpose or intention. For example, in the sentence 至于学习中文, 我很感兴趣 (zhìyú xuéxí zhōngwén, wǒ hěn gǎnxìngqù), the phrase 至于学习中文 (zhìyú xuéxí zhōngwén) means "with regard to learning Chinese". The rest of the sentence, 我很感兴趣 (wǒ hěn gǎnxìngqù), means "I am very interested". So, the whole sentence means "With regard to learning Chinese, I am very interested".至于 is a versatile word that can be used in a variety of contexts. It is an important word for HSK learners to know, as it can help them to express themselves more clearly and accurately in Chinese.
