+# China Region Build — Design Document
+
+Date: 2026-04-03
+Branch: `feat/deploy_cn`
+
+## Background
+
+Due to compliance requirements, the site needs a separate China version with:
+- Route/page-level hiding (whitelist model — only explicitly allowed pages are included)
+- In-page section-level filtering (remove specific headings/paragraphs)
+- Independent API endpoints pointing to China infrastructure
+- Deployed to an independent domain (e.g., `open.longbridge.cn`)
+
+## Core Approach: Build-Time Separation
+
+Use environment variable `VITE_REGION=cn` to produce a completely independent static build. The China build artifact contains **zero traces** of excluded content — no HTML, no JS chunks, no sitemap entries.
+
+## Configuration
+
+### `region.config.ts` (project root)
+
+Centralized whitelist + section exclusion config:
+
+```typescript
+import type { RegionConfig } from './docs/.vitepress/types'
+
+export const regionConfig: Record<string, RegionConfig> = {
+  cn: {
+    // API endpoints
+    apiBaseUrl: 'https://openapi.longbridge.cn',
+    portalGatewayBaseUrl: 'https://m.longbridge.cn',
+
+    // Whitelist — only matched pages are built into China version
+    // Uses glob patterns via micromatch, ** prefix matches all 3 locales
+    includePages: [
+      '**/docs/index.md',
+      '**/docs/getting-started.md',
+      '**/docs/changelog.md',
+      '**/docs/cli.md',
+      '**/docs/sdk.md',
+      '**/docs/quote/**',
+      '**/docs/socket/**',
+      '**/docs/qa/**',
+      '**/api/**',
+    ],
+
+    // In-page section exclusion (within whitelisted pages)
+    excludeSections: [
+      {
+        page: '**/docs/getting-started.md',
+        headings: ['US Stock Trading', '美股交易', '美股交易'],
+      },
+    ],
+  },
+}
+```
+
+### Key Design Decisions
+
+1. **Whitelist model** — New pages are excluded by default; must be explicitly added. This is the safe default for compliance.
+2. **Glob patterns with `**` prefix** — One rule covers all 3 locales (en, zh-CN, zh-HK). All 3 languages are preserved in China version.
+3. **`micromatch` for matching** — Already a VitePress dependency, no new packages needed.
+4. **Filtering inside VitePress pipeline** — Not post-build file deletion. Ensures JS bundles, route manifests, and search indices are all clean.
+
+## Build Script
+
+```jsonc
+// package.json
+{
+  "build:cn": "cross-env VITE_REGION=cn VITE_API_BASE_URL=https://openapi.longbridge.cn VITE_PORTAL_GATEWAY_BASE_URL=https://m.longbridge.cn vitepress build docs"
+}
+```
+
+## Integration Points
+
+| Integration Point | File | What Changes |
+|-------------------|------|-------------|
+| **Route generation** | `docs/.vitepress/utils.ts` — `rewriteMarkdownPath` | Pages not in whitelist return empty/excluded, VitePress skips route generation |
+| **Sidebar generation** | `docs/.vitepress/theme/utils/gen.ts` — `genMarkdowDocs` | Filter files against `includePages` during directory traversal |
+| **In-page section removal** | `docs/.vitepress/md-plugins/region-filter.ts` (new) | Markdown-it plugin: parse AST, match headings from `excludeSections`, remove heading + content until next same-level heading |
+| **Sitemap** | `docs/.vitepress/config.mts` — `sitemap.transformItems` | Filter out excluded pages |
+| **LLMs.txt** | `scripts/generate-llms.ts` | Skip excluded pages during generation |
+
+## Deployment
+
+### OSS Paths
+
+- Global: `oss://lb-assets/github/release/open.longbridge.com/new-docs/raw/`
+- China: `oss://lb-assets/github/release/open.longbridge.cn/new-docs/raw/`
+
+### CI/CD
+
+Add `deploy-cn` job to `.github/workflows/release.yml`, running in parallel with the global deploy job:
+
+```yaml
+deploy-cn:
+  runs-on: ubuntu-latest
+  steps:
+    - uses: actions/checkout@v4
+      with:
+        submodules: true
+    - run: bun install
+    - run: bun run build:cn
+    - name: Upload to Aliyun OSS (CN prefix)
+      run: |
+        aliyun oss sync docs/.vitepress/dist/ \
+          oss://lb-assets/github/release/open.longbridge.cn/new-docs/raw/ \
+          --force --update
+    - name: Deploy to Cloudflare Pages
+      uses: cloudflare/pages-action@v1
+      with:
+        projectName: openapi-cn
+        directory: docs/.vitepress/dist
+```
+
+Both global and China versions deploy from a single push to `main` / `release`.
+
+## File Change Summary
+
+| Action | File |
+|--------|------|
+| **New** | `region.config.ts` — Whitelist + section exclusion config |
+| **New** | `docs/.vitepress/md-plugins/region-filter.ts` — Markdown section removal plugin |
+| **Modify** | `docs/.vitepress/utils.ts` — Route filtering by whitelist |
+| **Modify** | `docs/.vitepress/theme/utils/gen.ts` — Sidebar filtering |
+| **Modify** | `docs/.vitepress/config.mts` — Sitemap filtering + region config loading |
+| **Modify** | `scripts/generate-llms.ts` — LLMs.txt filtering |
+| **Modify** | `package.json` — Add `build:cn` script |
+| **Modify** | `.github/workflows/release.yml` — Add `deploy-cn` job |
+
+## Implementation Phases
+
+### Phase 1: Foundation
+- Create `region.config.ts` with type definitions
+- Add `build:cn` script to `package.json`
+- Implement region config loading utility (read `VITE_REGION` env)
+
+### Phase 2: Page-Level Filtering
+- Modify `genMarkdowDocs` to filter sidebar entries
+- Modify `rewriteMarkdownPath` to exclude non-whitelisted routes
+- Filter sitemap entries
+
+### Phase 3: Section-Level Filtering
+- Implement `region-filter.ts` markdown-it plugin
+- Register plugin in VitePress markdown config
+
+### Phase 4: Build Verification
+- Run `build:cn` and verify:
+  - Excluded pages have no HTML files in dist/
+  - Sidebar doesn't show excluded pages
+  - Sitemap doesn't contain excluded URLs
+  - Excluded sections are removed from whitelisted pages
+  - API base URL points to CN endpoint
+
+### Phase 5: CI/CD
+- Add `deploy-cn` job to release workflow
+- Configure OSS CN prefix path
+- Configure Cloudflare Pages CN project
