Getting through the Immigration Agency: Taking a number and explaining why you're here

💬 延期 (yán qī) can mean "extend", as here, but it also commonly means "postpone". A 延期 meeting has been pushed back, so the context tells you which one is meant.

💬 The pattern is 我要辦 + the thing you need, and it's the simplest way to state your business at any office. You could also say 我要辦居留證 "I'm here to apply for a resident certificate".

💬 都 (dōu) means "all, both" and always goes before the verb, never after it like English "brought them all". It refers back to the things already mentioned, as in 都買了 "bought them all".

💬 Chinese has no single word for "yes". You answer by repeating the verb from the question, so 有帶嗎？ "Did you bring them?" gets 有 for yes.

💬 Adding 嗎 (ma) to the end of a statement turns it into a yes/no question, and nothing else moves. 是這個按鈕 means "It's this button", and 是這個按鈕嗎？ means "Is it this button?"

🇹🇼 Numbers are usually announced by an automated voice in Mandarin and shown on screens with a counter number. Watch the screen rather than relying only on the audio.

💬 多久 (duō jiǔ) asks "how long" and goes after the verb, at the end. The same pattern works elsewhere: 要坐多久？ "How long is the ride?"

💬 多 (duō) "many" works on its own as the description, with no 是 needed. Put 不 in front to say "not many", or flip it to 現在人很多 "It's busy now".

💬 In 二十 (èr shí) you use 二, not 兩. 兩 (liǎng) is for counting things directly, as in 兩分鐘 "two minutes", but in bigger numbers like twenty it's 二.

💬 客氣 (kè qi) means "polite, standing on ceremony", so 不客氣 (bú kè qi) is literally "don't be so polite". 不 is said (bú) here because it comes before the falling tone (kè).
