Last updated: July 2026
China’s social media ecosystem is dominated by a distinct set of platforms — WeChat, Douyin, Xiaohongshu, Weibo, Kuaishou, Bilibili, and Zhihu — each with its own advertising policies that layer on top of national advertising law. For foreign marketers, navigating each platform’s content rules, approval processes, and restricted categories is essential to campaign success. This quick reference guide provides a side-by-side comparison of the major platforms’ advertising policies, including prohibited content, review processes, and compliance best practices.

Platform-by-Platform Policy Reference
1. WeChat (微信) — Tencent
Moments Ads Official Accounts Mini Programs Strict Health Review
Key Advertising Policy Points
- Moments Ads (朋友圈广告): Videos limited to 6–60 seconds; images 6–15 images maximum; must include explicit “广告” (advertisement) label; cannot be posted by personal accounts without Tencent Ads authorization
- Official Account Ads: Native ads in article footer or embedded; must not interrupt reader experience; promoted content must be clearly distinguished from editorial content
- Mini Program Ads: Banner ads, interstitial ads, and reward video ads are supported; must follow Tencent’s UI guidelines
Prohibited Categories
- Tobacco products and e-cigarettes (all forms)
- Adult content and services
- Gambling and gambling-related content
- Unregistered pharmaceuticals and medical devices
- Political and religious advertising
- Weapons, ammunition, and protective gear
Approval Process
WeChat operates a two-tier review system. After creating an ad in Tencent Ads Manager, it undergoes an automated AI review (typically 30 minutes), followed by a manual review (1–24 hours depending on category). Health, food, and financial ads require additional documentation upload. Ads for medical and pharmaceutical products must first obtain SAMR pre-approval before submission to the platform.
Foreign Brand Considerations
- Brands must register through Tencent’s official ad partner program or work with a certified Tencent Ads Agency
- Cross-border advertisers may need to provide additional business license documentation
- WeChat now requires real-name verification for all advertising accounts
- International payment (foreign credit cards) is supported through select agency partners
Best Practice: WeChat Moments ads targeting first-time users in China perform best with soft-sell, culturally resonant content rather than direct product pitches. Engagement rates increase 40–60% for ads that use Chinese cultural references or seasonal themes.
2. Douyin (抖音) — ByteDance
Short Video In-Feed Brand Takeover KOL Integration
Key Advertising Policy Points
- In-Feed Ads: Full-screen vertical video (9:16 ratio); 5–60 seconds; auto-play with sound on — user can skip after 2 seconds; must include “广告” label overlay
- Brand Takeover: Single-day exclusive splash screen ad; extremely limited availability; must be booked 2+ weeks in advance
- TopView: Full-screen immersive ad when user first opens the app; 60-second maximum
- Live-Streaming Ads: Hosts must be registered influencers; real-time content review applies
- Dou+ (付费推广): Content amplification tool — boosted content must still comply with advertising rules, even though it is promoted through a content tool rather than the ad platform
Prohibited Content
- Superlative language without supporting evidence (same as national law but strictly enforced)
- Misleading before-and-after comparisons (especially for beauty, fitness, and health products)
- Content that challenges public order or social norms
- Unlicensed cross-border product sales through ad links
- Clickbait or misleading call-to-action overlays
Approval Process
Douyin’s review is primarily AI-driven with manual escalation. Standard ads are reviewed within 1–4 hours. High-risk categories (health, finance, food) require manual review and additional documentation. Douyin’s system cross-references claims against a database of SAMR enforcement actions.
3. Xiaohongshu (小红书 / RED)
Sponsored Notes Authenticity KOL Disclosure
Key Advertising Policy Points
- Sponsored Notes (赞助笔记): Brands must use the platform’s “Brand Partner” (品牌合作) tool for all sponsored content; influencers cannot independently post paid content without platform registration
- Disclosure Requirements: All sponsored content must carry the “赞助” (sponsored) or “广告” (advertisement) tag provided by the platform; non-disclosed sponsored content is a serious violation
- Search Ads: Keyword-targeted ads appear in search results alongside organic content; must be clearly marked
- Brand Zone: A curated brand landing page within Xiaohongshu; requires brand verification
Prohibited Practices
- Fake reviews, fake engagement, or paid reviews that do not reflect genuine user experience
- Content that impersonates ordinary user posts (all brand-sponsored content must be identifiable)
- Exaggerated product claims — Xiaohongshu’s community ethos centers on “authentic sharing”
- Medical claims for non-medical products (cosmetics cannot claim therapeutic effects)
Critical for Foreign Brands: Xiaohongshu has been a key enforcement focus for SAMR regarding undisclosed influencer advertising. In 2025, the platform worked with SAMR on a compliance campaign that flagged over 8,000 non-disclosed sponsored posts, resulting in penalties for both brands and influencers. Always use the official Brand Partner tool.
4. Weibo (微博)
Feed Ads Fan Head Topic Ads
Key Advertising Policy Points
- Feed Ads: Appear in the user’s home feed; support images, video, and carousel formats; must include “推广” (promoted) label
- Fan Head (粉丝头条): A tool for boosting organic posts; boosted content must still comply with ad regulations
- Topic Ads: Brands can sponsor trending topics; must include “广告” label in topic header
- Super Topic: Brand-owned community spaces; promotional content within Super Topics must be clearly identified
5. Kuaishou (快手)
Short Video Live-Stream Grassroots Focus
Key Advertising Policy Points
- In-Feed Ads: Similar format to Douyin but with more flexible duration (5–120 seconds)
- Live-Stream Ads: Very prominent on Kuaishou; live-stream hosts require real-name registration and must comply with live-stream advertising rules
- Brand Takeover: Available but less expensive than Douyin’s equivalent
- Open Screen Ad: Available for daily or weekly booking
- Kuaishou “KOC” Ecosystem: Kuaishou emphasizes its key opinion consumer (KOC) model — everyday users who review products. All KOC promotions must be disclosed.
Content Restrictions
- No exaggerated “get rich quick” or financial scheme promotions
- Agricultural and food products must have relevant certifications displayed
- Live-stream hosts cannot make health or medical claims about products without appropriate licenses
- Alcohol advertising restricted to certain time periods and age-verified audiences
6. Bilibili (哔哩哔哩 / B站)
Long-Form Video Gen Z Up-video Integration
Key Advertising Policy Points
- Up-Video Integrations: The most popular ad format on Bilibili — content creators (UPs) integrate brand messaging into their videos. Must be disclosed in the video description and video itself
- In-Feed Ads: Appear in the recommendation feed; native video format
- Brand Zone: Custom brand page within Bilibili; content must align with Bilibili’s community culture
- Story Mode: Vertical short-video ads within the app’s story feature
Unique Rules
- Bilibili’s audience (predominantly Gen Z born after 1995) is highly sensitive to inauthentic advertising — disclosed, transparent sponsorships perform better than disguised ads
- Game advertising is a major category but requires game publishing license (版号) display
- Educational content promotions require school/institution license display
- Bilibili has voluntary content guidelines that exceed legal requirements in some areas (e.g., alcohol and gambling content)
7. Zhihu (知乎)
Q&A Native Content Professional Audience
Key Advertising Policy Points
- Native Content Ads: Brand-authored content that appears in Q&A feeds; must be marked as “品牌内容” (brand content)
- In-Feed Ads: Image or video ads in the recommendation feed
- Brand Questions: Brands can sponsor questions for community discussion; the sponsorship must be disclosed
- Salt (会员): Paid membership platform where some advertising restrictions differ
Content Standards
- Zhihu’s community emphasizes expertise and factual accuracy — ads must be substantiated at a higher standard than on other platforms
- Technical or scientific claims require citations and references
- Product recommendations in Q&A format must be genuine and disclosed
- Zhihu has banned certain “low-quality” ad formats including full-screen interstitials and auto-playing sound ads

Common Platform Compliance Pitfalls for Foreign Brands
- Using the wrong ad label: Each platform requires specific wording — “广告” (advertisement), “推广” (promoted), or “赞助” (sponsored). Using “合作” (collaboration) instead is insufficient and can result in rejection or retroactive penalties.
- Boosting organic content without disclosure: Using a platform’s “boost” or “promote” tool on an organic post turns it into advertising. Some foreign brands have been penalized for boosting posts that originally appeared organic without adding ad labels.
- Influencer posts without platform tool: On Xiaohongshu in particular, arranging an influencer to post about your product and then paying them outside the platform’s Brand Partner tool (even if the post carries a disclosure) is a violation.
- Cross-posting global campaigns: A campaign approved on Instagram does not automatically comply with Douyin or WeChat rules. Each platform has its own content policies that must be reviewed separately.
- Ignoring platform-specific category restrictions: A product that is freely advertised on Weibo may be restricted on Bilibili (e.g., alcohol advertising has different rules on each platform).
Ad Approval Optimization Checklist
To minimize rejection rates across platforms, confirm the following before submission:
- ☐ Advertisement carries the correct platform-specific label (广告/推广/赞助/品牌内容)
- ☐ All superlative claims have been removed or substantiated with verifiable evidence
- ☐ Influencer partnerships are registered through the platform’s official collaboration tool
- ☐ Product-specific regulatory approvals (where applicable) have been obtained and approval numbers are displayed
- ☐ Ad creative complies with platform-specific format requirements (aspect ratio, duration, file size)
- ☐ Landing page or Mini Program is compliant and functioning
- ☐ Chinese-language copy has been verified by a native speaker for accuracy and cultural sensitivity
- ☐ Third-party review has been completed for high-risk categories
- ☐ Campaign records are saved for the 3-year retention requirement
Platform Policy Update Frequency
Chinese social media platforms update their advertising policies frequently. Based on 2025–2026 data:
| Platform | Policy Update Frequency | How to Monitor |
|---|---|---|
| WeChat (Tencent) | Quarterly (major), Monthly (minor) | Tencent Ads official WeChat account; email notifications to ad account holders |
| Douyin (ByteDance) | Bi-monthly | Ocean Engine (巨量引擎) dashboard announcements; industry newsletters |
| Xiaohongshu | Quarterly | Brand Partner portal notifications; Xiaohongshu for Business blog |
| Semi-annually | Weibo Ads Center announcements | |
| Bilibili | Quarterly | Bilibili Advertising Platform updates; UP community posts |
Conclusion
China’s social media advertising ecosystem offers powerful reach for foreign brands — but the patchwork of platform-specific policies demands careful navigation. This quick reference guide provides the baseline information your team needs to approach each platform’s ad system with confidence. However, platform policies evolve rapidly. We recommend:
- Assigning a team member to monitor policy updates from each platform where you advertise
- Building a pre-submission compliance check into your campaign workflow that references platform-specific rules (not just national law)
- Maintaining a relationship with a certified platform agency partner who receives advance notice of policy changes
- Conducting quarterly audits of active campaigns to ensure ongoing compliance with current policies
By treating platform compliance as a distinct — but connected — layer beneath national advertising law, foreign brands can run successful campaigns across China’s diverse social media landscape while minimizing regulatory and reputational risk.
