Lesson 3

Thank You, Goodbye & Introducing Yourself
Xinxin reviewed greetings and pinyin pronunciation rules from Lessons 1–2, then taught every way to say thank you and goodbye, plus full name introductions from casual to ultra-formal. She also covered key phonetics rules — tone-mark placement, hidden vowels, the 日 vs 热 distinction, neutral tone, and 不/没 as two different negatives — and closed with the Chinese cultural concept of 贵人 and how to explain your character to a stranger.
Swipe left to start
When a syllable has more than one vowel, the tone mark goes on the vowel that opens the mouth widest — a > o > e > i > u. Xinxin explained this in Mandarin during the lesson.
a always wins
If there is an 'a' in the syllable, the tone mark always sits on it. No exceptions.
huā 花, guāng 光, xiāng 香
Mouth opening order: a > o > e > i > u
Xinxin said: 'When you say a, o, e, i, u, your mouth is getting smaller and smaller. So we put the tone mark on the one where your mouth is widest.' If there's an a, it always gets the mark.
xiāo: a gets it (not i or o last). guì: ui rule — last vowel gets it.
Several pinyin finals hide a vowel to keep the spelling short. Xinxin said: 'We add the o or e to make it complete in speech, but we omit one in writing so the pinyin is not too long.' Know the hidden vowel so your mouth opens correctly.
gui = g + u + ei
The 'i' in 'gui' is actually 'ei'. Open your mouth — don't purse your lips in an 'ooh-wee' shape. Relax and let 'ei' come out.
贵 guì (expensive), 会 huì (can/meeting), 规矩 guī ju (rules)
Open the mouth — the writing hides a vowel
The omitted vowel is the one that opens your mouth. When you feel yourself puckering or tensing your lips on a final, check if there is a hidden vowel you should be opening to.
gui: don't say 'goo-ee'. Open to 'g-wei'. iu: don't say 'ee-oo'. Open to 'ee-oh'.
Both characters start with 'r' but require different mouth positions. Cantonese and southern Mandarin speakers typically flatten both — Xinxin flagged this as a known Cantonese accent marker.
日 rì — tongue stays curled, mouth relatively closed
Tongue curls back (retroflex). Mouth stays smaller. Same tongue position as the 'r' initial in 热, but you don't open much. 日 also means the sun or a day.
日 rì (day/sun), 日本 Rìběn (Japan)
Mouth stays closed for 日, opens for 热
The 'r' retroflex tongue position is the same for both. What changes is the vowel: 'i' keeps the mouth narrow; 'e' opens it. Focus on the jaw movement, not the tongue.
日 rì: tongue back, mouth narrow. 热 rè: tongue back, then drop the jaw for 'e'.
When a syllable has no tone mark in pinyin, it is the neutral tone (轻声 qīng shēng). Xinxin: 'If you don't see the tone marker, we call it the neutral tone. Just pronounce it lightly.'
妈妈 māma — mā is 1st tone, ma is neutral
The second syllable is short and unstressed. The neutral tone has no fixed pitch — it follows naturally from the tone before it.
妈妈 māma (mum/mummy) — the second ma floats lightly
No mark = light and quick
The neutral tone is shorter and softer than any numbered tone. It does not have a set pitch contour — it blends with what comes before it. Do not give it full weight.
不好意思 bù hǎo yì si — the final si is neutral: short, unstressed, barely voiced.
不 is normally 4th tone (bù), but shifts to 2nd tone (bú) before any 4th-tone syllable to avoid two consecutive falling tones.
不 + 4th tone → 2nd tone
不 shifts from bù (4th) to bú (2nd) to avoid two consecutive falling tones — up then down flows more naturally than down then down.
不客气 bú kè qi, 不是 bú shì, 不用 bú yòng, 不会 bú huì
Falling + Falling = too heavy
Two 4th tones in a row feel abrupt and effortful. 不 softens to 2nd so the pair flows: up (bú) then down (4th tone). You hear this most in 不是, 不对, 不客气.
不客气: written bù kè qi → spoken bú kè qi. Rising 2nd + falling 4th feels smooth.
Both mean 'not' but work differently. Xinxin explained: '不 is usually used to negate the verb, the adjective, the adverb — to say not. 没 usually means something doesn't exist or didn't happen.'
不 bù — negate choices, states, future plans
Use 不 for something you choose not to do, or to describe a state. Present or future. Goes before verbs and adjectives.
我不吃 (I'm not eating / don't want to eat), 不忙 (not busy), 不工作 (not working / choosing not to work)
Choice or absence?
Ask: am I choosing not to, or describing a current/future state? → 不. Is something absent or did something not happen? → 没.
我不工作 (I choose not to work today) vs 没有工作 (there is no work / I have no job).
These two look similar but serve different purposes. Xinxin: '怎么 is like — how to do something. 怎么样 is how is something.'
怎么 zěn me — how to (do something)
怎么 asks about the method or means. It precedes a verb: 怎么去 (how to get there), 怎么读 (how to read it), 怎么写 (how to write it).
怎么去机场？ Zěn me qù jī chǎng? — How do I get to the airport?
Method vs evaluation
怎么 + verb = how to do. Topic + 怎么样 = how is it. When in doubt: if you can slot in 'how to' → 怎么; if 'how is it' → 怎么样.
怎么去 (how to go) vs 今天怎么样 (how is today). Never swap them.
Xinxin introduced 是 for self-introduction and yes/no questions, and flagged how it differs from English 'is/am/are'.
我是…… — I am…
是 connects two matching noun concepts: I = teacher, he = student. Do not use before adjectives — not 我是忙 (wrong).
我是老师。Wǒ shì lǎo shī. — I am a teacher.
是 only links nouns to nouns
If you can say 'A is B' where both A and B are nouns or noun phrases, use 是. If B is an adjective (busy, tired, hot), drop 是 and use the adjective directly, usually with 很.
我是学生 ✓ (noun). 我很忙 ✓ (adjective + 很). 我是忙 ✗ (adjective after 是 — wrong).
Xinxin explicitly corrected this: 没问题 does NOT answer 谢谢. It is only used when someone asks you to do a task.
没问题 = 'No problem' for tasks
Use 没问题 only when someone asks you to do something and you confirm you can do it. Xinxin: '没问题 is used when someone asks you to do a task: 没问题，我来做.'
A: 你能帮我吗？B: 没问题，我来做。— Can you help me? No problem, I'll do it.
没问题 = task confirmation, not gratitude response
In English 'no problem' doubles as a thank-you response. In Mandarin, 没问题 is specifically for capability/task contexts. For thanks, stick to 不客气 / 不用谢 / 没事.
Task: 没问题，我来做。Thanks response: 不客气. Never swap them.
Good morning (formal, late morning)
上午 = morning/AM. Reviewed at the lesson opening — Xinxin said it was morning in France so she greeted with 上午好.
Are you busy today?
Opening exchange of the lesson — natural small talk opener.
Excuse me / Sorry to bother you
Lighter than 对不起. For interrupting, minor inconvenience, asking a favour. The si is neutral tone.
Thank you
Second 谢 goes neutral. 谢谢你 = thank you specifically to you.
Goodbye (lit. see you again)
再 = again, 见 = to see/meet. More formal — use when you don't know the next meeting time.
To be called / to call (as a name)
The main verb for introducing names. 你叫什么 = what are you called. 我叫Loy = I'm called Loy.
Mr. / Sir
生 goes neutral. Surname + 先生 = 李先生 (Mr. Li). Xinxin used this example: 你可以叫我李先生.
Not eating / I won't eat
If someone offers food you don't want: 我不吃，谢谢. Add 谢谢 to be polite.
Refrigerator (lit. ice box)
Loy's observation: 'literally the ice box.' 冰 = ice, 箱 = box.
To learn / to study
Xinxin: 'The character xu — to learn. Generally xu, you can just say I learn something: 我学啊我学普通话.'
Loy's Chinese name (Li Guohao)
Xinxin: 'Guo is very common. This is quite popular name, especially in Hong Kong.' 李 (Li) is a very common family name.
Chinese has many homophones. When you give your name, people often don't know which character you mean — so explaining it is a standard social skill.
Method 1: Break the character into radicals
Describe the top/bottom or left/right components. Works when the character has clearly visible parts.
我姓李，木子李 — the Li with 木 on top and 子 below. Xinxin's surname: 关耳郑 — the Zhèng with 关 on the left and 耳 on the right.
Two methods, one goal
Either break the character into radicals (parts you can see) or reference a famous person whose name contains the same character. The goal is for the other person to picture the right character.
For 李: 木子李 (radical breakdown). For 成: 成龙的成 (celebrity reference). Pick whichever is clearer.
Xinxin introduced this concept near the end of the lesson. It has no direct English equivalent and reflects something important about Chinese social culture.
贵人 — someone pivotal in your life
A person who truly helps you succeed — opens doors, offers opportunities, gives life-changing advice. More than a mentor; someone whose help was transformative.
他是我的贵人 — He has been a true benefactor to me.
贵人 ≠ 师父 ≠ 朋友
贵人 is specifically someone who helped you at a pivotal moment — career, life decisions, major opportunities. It's not used for general friends or skill teachers. Saying 他是我的贵人 is a high compliment.
他是我的贵人，在我事业上给了我很多机会 — He is my benefactor; he gave me many opportunities in my career.
Say each phrase aloud before checking. Focus on the first syllable in each pair — that's where the change happens.
Written
hello
The classic. Both 3rd → first shifts to 2nd. This is the template for all 3+3 sandhi.
Spoken aloud
Cover the Chinese and try to produce it from the English, then check.
Translate into Mandarin
I'm not working today.
Word hints (scrambled)
Type the pinyin
Tone mark placement: a > o > e > i > u — always mark the widest-mouth vowel. If there's an 'a', it always gets the mark. iu and ui are exceptions: mark goes on the last vowel.
Hidden vowels: gui = g+u+ei (open mouth, don't purse), iu = i+ou (open mouth, don't tense), ian sounds like 'yen', un = u+en. The pinyin omits the middle vowel but you still pronounce it.
日 rì vs 热 rè: same curled tongue, different jaw opening. 日 = mouth stays narrow. 热 = drop the jaw for 'e'. Cantonese speakers often merge these — practise the jaw movement.
Neutral tone: no tone mark = say it lightly and briefly. Common in suffixes (子, 们, 的) and second syllables of repeated words (妈妈, 弟弟).
不 changes from bù (4th) to bú (2nd) before any 4th-tone syllable. Not before 1st, 2nd, or 3rd tone. Test: 不客气 → bú kè qi; 不好 → stays bù hǎo.
不 negates choices/states (present or future). 没 negates existence or past events. 我不工作 (choosing not to work) vs 没有工作 (no work exists).
怎么 = how to (do something) + verb. 怎么样 = how is (something) — follows a topic. Never swap them.
没问题 is ONLY for confirming a task ('no problem, I'll do it'). It is NOT a response to 谢谢. Use 不客气, 不用谢, or 没事 for thanks.
是 only links nouns. For adjectives, use the adjective directly with 很: 我很忙 (not 我是忙). Answer 是 questions with 对 or the verb, not just 是的.
Name introductions: casual 你叫什么名字 → formal surname 你姓什么 → respectful 您贵姓 → ultra-formal 您怎么称呼. Match the level to the situation.
When giving your surname, explain the character: break it into parts (木子李) or reference a celebrity (成龙的成). This is standard social practice.
贵人 (guì rén) = someone who is pivotal to your life and career. Distinct from 师父 (who teaches a skill). Introducing someone as your 贵人 publicly honours them and builds trust.
You correctly produced 我叫乐 and 我今天休息 without prompting, your 不好意思/没关系 recall from last lesson was immediate, and Xinxin noted your pronunciation was already noticeably better than Lesson 2.
DiSSS framework
Deconstruction
The hidden-vowel rules (gui = g+u+ei, iu = i+ou, ian = yen) are a single system: pinyin omits a vowel to save space, but you always pronounce it. Decode the rule once and it handles dozens of tricky syllables automatically.
Selection
Xinxin gave you exactly three registers for introductions: casual (你叫什么名字), formal surname (您贵姓), ultra-formal (您怎么称呼). Three patterns cover every social situation — nothing redundant, nothing missing.
Stakes
You have a real name to introduce — 李国豪 Lǐ Guóháo. Practise explaining 豪 the same way Xinxin explained 郑: find the character breakdown or a famous person whose name uses 豪 before next lesson.
Vocabulary context
The core vocabulary this lesson is HSK 1–2: greetings, thanks, goodbyes, basic negatives. The formal introduction phrases (您贵姓, 免贵, 称呼) are HSK 4–5 but appear in every professional first meeting in China — worth learning now despite the level.
Tomorrow's action
Before next lesson: practise saying 我姓李，木子李 and 我叫李国豪 out loud five times. Then find how to explain 豪 — either break it into radicals or find a famous person whose name contains it.
