01 · Our mission
Clear answers without pretending the subject is simple
China’s payment environment connects mobile wallets, bank rails, card networks, exchange controls, identity checks and provider-specific rules. Information is often scattered across technical documentation, policy notices and interfaces that change over time.
Extentage exists to organize that complexity into understandable, carefully qualified guidance. Our goal is not to remove every uncertainty; it is to show readers what is known, what depends on context and where official confirmation may still be required.
02 · Editorial scope
What Extentage covers
Consumer payments
Alipay, WeChat Pay, UnionPay, foreign-card linking, QR payments and common account limitations.
RMB and currency
CNY, CNH, reference rates, conversion concepts and the language used around China’s currency.
Business and suppliers
Payment methods, documentation, verification questions and risk-aware context for cross-border trade.
Troubleshooting and change
Common payment problems, product updates and policy developments that affect international users.

04 · How we work
Research is part of the product
We define the question, identify the strongest available sources, compare claims across evidence, distinguish rules from observed implementation and review material changes in context.
- Primary authorities and official provider material are prioritized where available.
- Publication dates, jurisdiction, account type and eligibility conditions are considered.
- Important uncertainty and conflicting evidence are disclosed instead of concealed.
- Guides are reviewed when meaningful rules, fees, workflows or interfaces change.
Our full source hierarchy and verification process are explained in How We Research.
05 · Editorial independence
Our conclusions are not for sale
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. Commercial arrangements must not determine factual conclusions, source selection or whether material limitations are mentioned.
Where affiliate links, sponsorships or other commercial relationships exist, they should be identified clearly and kept distinct from evidence-based editorial assessment. Read the complete Editorial Policy.
06 · Accountability
A publication should identify who stands behind it
Extentage Editorial
The publication is responsible for defining coverage, applying research standards, maintaining policy pages and reviewing correction reports. Individual author or reviewer details should be shown on articles where applicable, with material conflicts or commercial relationships disclosed in context.
Readers can challenge a claim through our Corrections Policy. Substantive reports are evaluated against the original evidence and current authoritative information.
07 · Boundaries
What Extentage does not provide
- Personalized legal, tax, investment, banking or regulatory advice
- A guarantee that a provider will approve an account or transaction
- Custody, exchange, remittance or payment-processing services
- A substitute for current provider terms or professional advice
- Official representation of any payment platform or public authority
Payment outcomes can depend on location, identity verification, account history, provider controls and changing regulations. Readers should confirm material decisions with the relevant provider or qualified professional.
