Publishing to Chinese social platforms

ReachWeaver prepares posts for Weibo (微博), Xiaohongshu / REDnote (小红书), Douyin (抖音), Bilibili (哔哩哔哩), WeChat Official Accounts (微信公众号), Zhihu (知乎), WeChat Channels (视频号), Kuaishou (快手), Toutiao (头条号), CSDN, Juejin (稀土掘金) and OSCHINA (开源中国). You post them yourself in the platform’s own app or creator site. ReachWeaver sends, uploads and schedules nothing on any Chinese platform.

Why it is manual

None of these platforms has an open posting API that ReachWeaver may use for you. The details are in the regional API feasibility study (read 2026-10-15/16):

Platform	Official posting API	What that means
WeChat Official Accounts	`draft/add` + `freepublish/submit`	Only for verified enterprise accounts since July 2025; personal accounts lost it. ReachWeaver has no adapter.
Douyin	`create_video`	Test-stage “Capability Lab” permission; publishing norms bar marketing content and individual businesses.
Weibo	`statuses/share` only	A link-share widget for the app’s own domain, not general posting.
Xiaohongshu	none open	Only `basic_info` is open; `write_notes` is “planned”.
Bilibili, Kuaishou, WeChat Channels	not verified / none found	Native upload only.

Browser automation of these sites is out of scope (browser-assist decision).

No account yet, or the sign-up form is in a language you do not read? reachweaver account-kit --platform weibo --persona work prepares your nickname, e-mail, phone and bio in Simplified Chinese and lists the form labels (注册, 手机号, 验证码, 实名认证 and more) with their English meaning. You create the account and complete every code and identity check yourself (account kit).

Prepare a post

reachweaver manual-export --platform weibo --variant weibo.json --out exports/weibo-launch

{
  "platform": "weibo",
  "text": "ReachWeaver 是一个离线优先的开源工具，帮你准备社交媒体帖子。#开源工具# https://example.org/docs",
  "platform_options": {"topics": ["开源工具", "开发者社区"]}
}

text is the exact post body. platform_options.title is the title (Xiaohongshu, Bilibili, WeChat, Zhihu).
platform_options.topics is a list of topic words without #. ReachWeaver writes them in the platform’s own syntax to topics.txt (Weibo #开源工具#, Xiaohongshu #开源, Bilibili a comma-separated tag list). It never adds them to your post text.
Output: post.txt (and title.txt, topics.txt), CHECKLIST.md and manual-export.json, in a new 0700 folder. Status is always manual_export_not_published.
Several posts at once: manual-export-batch with Asia/Shanghai times such as "at": "2026-11-02T20:00:00+08:00". The time is advisory; nothing is scheduled. See MANUAL-EXPORT.md.

What the package checks

Platform	Check	Status	Source
Weibo	Post up to 5,000 characters (“最多可以发布5000汉字”); over it blocks	verified	Weibo FAQ 21510
Weibo	Topics are `#话题词#`, 4 to 32 characters, no `# @ < > &` or line breaks; a `#tag` without the closing `#` warns	verified	Weibo FAQ 14734
Weibo	Each image under 20 MB (with `--media`); over it blocks	verified	Weibo FAQ 12483
Xiaohongshu	Title 20, counted the way the creator page counts it (ASCII is half a character); body 1,000; at most 10 topics	creator page code	creator.xiaohongshu.com
Bilibili	Title under 80, description under 250, tags under 200 in total	developer API	Bilibili open platform
WeChat Official Accounts	Title 32, content under 20,000 characters	developer API	draft_add
Douyin	Text up to 1,000 characters	developer API	create_video
All	Text with no Chinese characters warns: have a fluent reader review the Simplified Chinese	ReachWeaver rule	registry China note
All	Placeholders, control characters and Trojan Source characters block	ReachWeaver rule	MANUAL-EXPORT.md

Only verified limits (an official help, rule or legal page) block. A limit read from a creator page’s own code, or from a developer API reference, is a warning: the page can change at any redeploy, and the in-app composer may differ from the API. Anything else reads limit unknown — check the platform. Every fact in manual-export.json carries its source URL, the date it was checked (2026-10-17), the Chinese quote and an English translation.

Decisions only you make

Each package lists these with nothing pre-selected:

AI-generated content label (ai_generated_label). China’s Measures for Labeling AI-Generated Synthetic Content (《人工智能生成合成内容标识办法》, in force since 2025-09-01) Article 10: “用户使用网络信息内容传播服务发布生成合成内容的，应当主动声明并使用服务提供者提供的标识功能进行标识” (users who publish generated or synthesized content must declare it and label it with the platform’s labelling function) (CAC). If Claude or another assistant drafted the text, it may well count. Use the composer’s own option, for example Xiaohongshu’s “笔记含AI合成内容” or Douyin’s “内容由AI生成”. Douyin says undeclared AI videos get limited distribution (Douyin).
Advertising label (advertising_label). SAMR Internet Advertising Measures Article 9: ads must be identifiable, and promotion through reviews or experience posts with a purchase link must be marked “广告” (SAMR). Xiaohongshu also asks you to declare sponsorship (利益相关) and to run brand deals through 蒲公英.
Originality (originality). WeChat: marketing content may not be declared original (原创声明), and misuse removes the feature permanently (WeChat rules). Bilibili: choose 自制 (original) or 转载 (repost, with its source).

Other notes in the checklist: a WeChat subscription account can mass-send once a day and a service account four times a month (Tencent support); Xiaohongshu’s creator page can schedule a note 1 hour to 14 days ahead (native scheduling, not ReachWeaver); Zhihu’s user agreement requires a prominent label on AI-made content (Zhihu terms).

After you post

Keep the native post URL: it is the only evidence that a post exists. Record it with reachweaver mark-shared --platform weibo --text "..." --url URL so the repeat guard warns you before the same wording goes out again. Views and likes come only from the platform’s own analytics; with --url you can record them on the printed post id with reachweaver metrics or import-metrics (measure posts you shared by hand).

Limits of this guide

No row is legal advice, and no row says your account is eligible for anything. Check each platform’s current rules yourself before you post.
Douban, Maimai, Qzone and Tieba stay human-only: ReachWeaver writes no post text for them and gives you a notes form instead.
A WeChat Official Accounts adapter would need a verified enterprise account, the owner’s security review and a supervised live test. None exists.
