WeChat, Weibo & Social Media

The Chinese internet, in the vocabulary it uses

The Chinese internet is a parallel universe. WhatsApp, Messenger, Venmo, Uber, and Signal collapse into one app called 微信. Twitter's niche is filled by 微博. TikTok is an export of the original, 抖音. Instagram and Pinterest merge into 小红书. The apps are different, the interaction verbs are different, and the slang rolls over every six months.

This article is a snapshot. The nouns for the major platforms are stable; the verbs for chatting, posting, paying, and calling out a meme are the working vocabulary of anyone under sixty with a phone. Getting comfortable with them is how you stop being a tourist online.

1. The platform map

Eight apps do most of the work. Learn the names and the one-line pitch for each — when a coworker says "I saw it on 小红书" you need to know what kind of content that implies.

2. addContact() on WeChat

Adding someone on WeChat is the Chinese equivalent of the business-card exchange, the phone-number swap, and the "follow me on Instagram" moment rolled together. There are two standard mechanisms: a QR code scan, and a direct ID lookup.

The canonical exchange when meeting someone new:

3. chat() — messaging verbs

The basic chat surface. Three media types (text, voice, video), two call types (voice, video), and a whole sub-economy built on stickers.

Stickers: the second language

Chinese chat runs on stickers the way English chat runs on emoji. Everyone curates a personal collection; there is a whole subculture of sticker battles.

4. Social actions

The social graph inside WeChat is called 朋友圈 — literally "friend-circle" — and it's a feed of posts visible only to your mutual contacts. Outside WeChat, on Weibo / Xiaohongshu / Douyin, the actions map directly onto Western conventions: follow, like, comment, share.

5. Red packets & payments

China skipped the credit-card era. Most daily payments are QR-based, split between WeChat Pay and Alipay. The gift-money tradition — red envelopes at New Year and weddings — went digital early and is now a casual social gesture, a thank-you, a splitting-the-bill tool.

6. Content & trends

The trending-and-meme vocabulary. Much of it rotates every few months, but these structural terms — what counts as trending, what a meme is, how livestream commerce works — are stable.

8. Edge cases

Privacy: don't repost someone's Moments

朋友圈 is a semi-private space. Screenshotting someone's post and forwarding it outside their friend circle — or onto Weibo, where it becomes public — is a real breach of etiquette. If you want to reshare, ask first, or lean on 转发 within the app so the original poster controls reach.

三天可见 — the friction knob

A common privacy setting is 仅三天可见 (jǐn sān tiān kě jiàn) — "only visible three days." Anyone visiting your profile sees only posts from the last 72 hours; everything older is hidden. Variants: 半年可见 (half a year), 一个月可见 (one month). If you add a new contact and their 朋友圈 looks sparse, this is usually why — not that they don't post, just that you can't see the archive.

Voice messages vs text — a generational split

Older users (40+) lean heavily on 语音. It's faster to speak than to tap characters, and typing was never natural for people who learned writing by hand. Younger users find voice messages annoying — you can't skim them, can't search them, can't read them silently in a meeting. The polite move with a senior relative is to accept voice; the polite move with a peer is to send text unless there's a specific reason not to.

Registering without a Chinese phone number

Signing up for WeChat, Weibo, Alipay, and most domestic apps increasingly requires a mainland Chinese phone number and often a mainland ID document. The requirement tightens every year. Workarounds — borrowed phones, helpful friends, overseas SIM + help from a contact — exist but are fragile. If you plan to live in China, getting a local number is step zero; every other service hangs off of it.

微信 vs WeChat (the international version)

The app installed outside China is technically the same binary but routes through different servers, enforces different moderation, and can't always talk to Mainland-registered accounts transparently. Payments especially are fragmented: a foreign WeChat account may not be able to receive 红包 from a Mainland account, and vice versa. When in doubt, ask which version your counterpart is on.
