Essential Basics

Saying Yes, No and 'I Don't Understand' in Mandarin

There is no plain 'yes' or 'no' in Mandarin. Instead you repeat the verb in the question: if someone asks 要吗? (do you want it?), you answer 要 (want) or 不要 (don't want). It sounds strange for the first day and then becomes obvious.

Below are the short answers that cover most travel situations, plus the rescue lines that keep a conversation from collapsing when it moves past what you have memorized.

Quick yes and no

Chinese Pinyin English Listen
是 shì yes / it is Answers a question about what something *is*. 你是游客吗? — 是。
对 duì right / correct Confirms what someone just said. 对 is one of the most-used words in conversation.
不是 bú shì no / it isn't The negation of 是. Note the tone: 不 shifts to bú before a fourth tone.
对,不对 duì / bú duì right / wrong Handy when a driver repeats your destination back and you want to confirm or correct it.
好 hǎo OK / fine Agrees to a suggestion. 好的 hǎo de softens it further.
可以 kěyǐ can do / that's fine Answers a permission question, e.g. 可以刷卡吗? — 可以。
不行 bù xíng no, that won't do Firmer than 不要. You will hear it from staff about rules and closing times.

When you lose the thread

Chinese Pinyin English Listen
我不懂 Wǒ bù dǒng I don't understand Means 'I don't get it'. Use it when the words are clear but the meaning is not.
我听不懂 Wǒ tīng bù dǒng I don't understand what you're saying More specific: you cannot follow the speech. This is the one you will use most.
我不会说中文 Wǒ bú huì shuō Zhōngwén I don't speak Chinese Note 会 huì for a learned skill. Say it with a smile and people usually slow down.
你会说英语吗? Nǐ huì shuō Yīngyǔ ma? Do you speak English? Ask before launching into English. Many younger staff in cities can help, especially in hotels.
请再说一遍 Qǐng zài shuō yí biàn Please say that again 遍 biàn is the measure word for 'a time' here, not 次 cì.
请说慢一点 Qǐng shuō màn yìdiǎn Please speak a little slower 一点 yìdiǎn means 'a bit'. Swap it in elsewhere: 便宜一点 — a little cheaper.
请写下来 Qǐng xiě xiàlái Please write it down Excellent for addresses. A Chinese character written on paper beats three attempts at a taxi.
你能帮我吗? Nǐ néng bāng wǒ ma? Can you help me? 能 néng is about ability. 你能帮我吗? is a direct, acceptable way to ask a stranger.

The pattern behind it

If a question contains a verb, answer with that verb. 要吗? → 要. 有吗? → 有. 去吗? → 去. Negate by adding 不 in front. Learn the pattern once and you can answer questions you have never heard before.

Confirmation questions that end in 吗 are the easiest to handle, and they are everywhere: 有吗, 辣吗, 可以吗. Listen for the last syllable and mirror it back.
