至于 (with regards to)

• Pinyin: zhìyú
• Formation: 至于 + Topic，Comment / Explanation
• Hanzi breakdown: 至 = 一 (one) + 厶 (private) + 土 (earth) — to arrive; 于 = function word (at/in)

Meaning

The conjunction 至于 (zhìyú) means 'as for' or 'with regards to' and is used to shift the discussion to a different but related topic. It signals that the speaker is setting aside the current point and moving on to address another aspect.

While 关于 introduces the overall subject of a discussion, 至于 specifically transitions to a secondary or supplementary topic that the speaker wants to address separately. It often implies a contrast or a deliberate shift in focus: 'We've covered X; as for Y...' 至于 can appear at the beginning of a sentence or after a comma in a compound sentence. It frequently pairs with phrases expressing uncertainty or deferred decisions (至于...再说吧). Compared to 对于 which targets a specific aspect for commentary, 至于 carries a stronger sense of topic-switching. In some contexts, 至于 can also mean 'to the point of' or 'to go so far as' (often in negative form: 不至于), but this is a separate usage from the topic-shifting function.

Examples

1. 住宿的问题我已经安排好了，至于交通，你自己想办法吧。 I've already arranged the accommodation; as for transportation, you'll have to figure it out yourself.
2. 工作上的事我可以帮你，至于私事，我就不方便过问了。 I can help you with work matters, but as for personal affairs, it's not appropriate for me to get involved.
3. 至于他为什么突然辞职，到现在谁也说不清楚。 As for why he suddenly resigned, no one can explain it even now.
