Trust & transparency
Editorial Policy
How Extentage researches, reviews and maintains independent guidance about payments, currencies and commercial systems connected with China.
Independent
Editorial conclusions are not controlled by payment providers or sponsors.
Source-led
Primary documentation and authoritative evidence come first.
Reviewed
Material claims are checked for clarity, context and currency.
Correctable
Readers can report errors and substantive corrections are reviewed.
01 Our purpose
Clear guidance without disguised promotion
Extentage publishes independent educational information about payment systems, currencies, banking practices, supplier payments and cross-border transactions connected with China. Our purpose is to make complex topics understandable for international users without presenting promotional material as independent guidance.
We distinguish explanation from recommendation, identify important limitations and avoid implying certainty where rules, eligibility or provider behavior can vary.
02 Independence
Editorial decisions remain separate
Extentage is not affiliated with Alipay, WeChat Pay, UnionPay, a bank, wallet provider or government authority unless a relationship is explicitly disclosed on the relevant page. Those organizations do not approve our conclusions, select our coverage or receive favorable treatment.
03 Evidence standards
How we select and attribute sources
We prioritize sources closest to the underlying rule, feature or event. When a subject changes quickly, readers should consider the publication and review dates alongside the information presented.
Primary authorities
Regulations, central-bank material, government notices and official legal texts.
Provider documentation
Official help centers, product terms, fee schedules and operational guidance.
Direct verification
Observed workflows, documented transactions and reproducible product behavior.
Credible analysis
Established reporting and specialist analysis used with clear attribution.
Anonymous claims, unsourced social posts and copied summaries are not treated as sufficient evidence for material factual conclusions.
04 Quality control
Our review and maintenance process
Define the reader’s question
Coverage begins with a practical problem and the decisions a reader must make.
Research authoritative evidence
Material claims are checked against the strongest available current sources.
Review clarity and context
Drafts are checked for unsupported certainty, missing limitations and confusing language.
Monitor and update
Important guides may be revised when rules, product availability, fees or operational requirements change.
05 Reader safeguards
Financial information and limitations
Rates, examples, comparisons and payment information are provided for general educational purposes. They are not financial, legal, tax or investment advice and should not replace confirmation from the relevant provider or a qualified professional.
- Exchange rates and fees can change after publication.
- Eligibility and wallet functionality may vary by location, identity status and account history.
- Examples illustrate a process; they do not guarantee an identical outcome.
- High-value or regulated transactions warrant direct professional confirmation.
06 Accountability
Corrections and reader feedback
If you believe information is inaccurate or incomplete, send the page address, the issue you identified and any supporting source. We review substantive reports and correct the published material when warranted.
Found something that needs review?
Clear evidence helps us investigate quickly and keep the knowledge base useful.
07 Disclosure
Commercial transparency
Any sponsorship, affiliate relationship or other material commercial connection affecting a page will be disclosed clearly where readers can see it. Commercial considerations do not determine our factual conclusions. Sponsored material, if published, will be visibly labeled and kept distinct from independent editorial guidance.
Extentage does not accept payment in exchange for undisclosed endorsements, favorable factual conclusions or the removal of accurate criticism.
