The Chinese hello that isn't a question, and the goodbye that won't end

The neighbour on the third-floor landing looks up from her plastic bag of greens and asks whether you have eaten. You start to explain — noodles, around noon, not much — and by the second clause she has already nodded, shifted the bag to her other hand, and started up the stairs. You answered a question she did not ask.

The question that isn't one

Chī le ma (吃了吗), have you eaten, is not an enquiry into your lunch. It is closer to a nod given in words, the sound one neighbour makes so another knows they were seen. The correct reply is short — chī le, eaten, or the same question turned back — and then both of you move on. A full account of the meal is the wrong currency; it treats a greeting as an interview.

The other one you will hear is qù nǎr (去哪儿), where are you going. On a xiaoqu (小区) path between apartment blocks, or at the mouth of a Beijing hutong (胡同) where the vegetable seller keeps a stool, it lands the same way. Nobody wants your itinerary. Chū qu yīxià (出去一下), just heading out, closes it politely and gives away nothing. The dàmā (大妈) who asked has already read what she needed from your bag and your direction.

The vocabulary of leaving

Watch a small restaurant when a table stands to go. Someone by the till will call màn zǒu (慢走), walk slowly, at your back — not advice about your pace, but the standard seam that closes a visit. You are not expected to slow down or to answer; a small lift of the hand is enough. In a noodle shop the cook may say it without looking up from the pot.

The register widens with the weather and the hour. Màn diǎn (慢点), take it slow, comes when the floor is wet; lù shang xiǎoxīn (路上小心), care on the road, follows you into the dark when you leave a home after dinner. These are not instructions. They are the spoken equivalent of a hand on the door, held a second longer than it needs to be.

Being seen off

Leaving a Chinese home is rarely a single motion. The host rises with you, and what looks like the end of the evening is the start of a second, slower ritual: sòng kè (送客), seeing the guest out. In an apartment this often means walking you to the lift and holding the door with a flat palm while you step in; in a house with a courtyard it can mean walking to the gate, and sometimes to the corner where you catch a car.

Somewhere in this you may hear liú bù (留步), stay your steps — your cue to tell the host to go no further, which they will likely decline at least once before agreeing. The choreography is the point. To let yourself be walked out, to protest gently, to wave from the lift as the doors close, is to accept the warmth rather than cut it short. Bolting for the door with a quick thanks can read as a door shut on an outstretched hand.

The reply that keeps it open

Much of this depends on not being literal, and on not being the one who ends things too soon. When a host waves off your thanks with bié kèqi (别客气), don't stand on ceremony, the answer is not to take them at their word and drop the courtesy — it is to stay warm while easing off. Kèqi (客气) is the politeness everyone insists you abandon and nobody entirely does.

Praise works the same way. Compliment a home-cooked dish and the cook may bat it away with nǎli nǎli (哪里哪里), roughly where, where — a reflexive deflection, not fishing. Agreeing outright can feel abrupt; the softer move is to praise a specific thing, the fish, the way the rice came out, so the deflection has somewhere to land. Enthusiasm is welcome. It just travels better attached to a detail than to a superlative.

这些话不是问句，而是一种把人放在心上的方式。

Where the codes run deepest

You will feel all of this most in older residential compounds, county towns, and family homes, where neighbours still know each other by floor and surname. In the cafes of central Shanghai or Shenzhen the greetings thin out, replaced by the same clipped service scripts you would meet anywhere; a barista is unlikely to ask if you have eaten. Go where daily life still happens on foot — a morning market, a stairwell, a shop with a stool out front — and the vocabulary returns.

The one mistake worth avoiding is treating any of it as a request for information. Answering chī le ma with a menu, or leaving a home before your host has finished seeing you off, does not offend so much as mark you as someone reading the words and missing the gesture. If you are unsure how far to protest or how long to linger at the lift, watch what the other guests do and follow by a half-second; the rhythm is easy to catch once you stop listening for content. There is nothing to book and no fee to confirm here — only a register to notice, and the small, unhurried courtesy of matching it.
