[firstdata-dev]

Summary

Adding 5 new Chinese authoritative data sources (morning batch, 2026-05-05).

New Sources

ID	Name (EN / ZH)	Category	Authority
china-abc	Agricultural Bank of China / 中国农业银行	finance/banking	commercial
china-ccb	China Construction Bank / 中国建设银行	finance/banking	commercial
china-psbc	Postal Savings Bank of China / 中国邮政储蓄银行	finance/banking	commercial
china-chinalife	China Life Insurance / 中国人寿保险	finance/insurance	commercial
china-vip	VIP (Chongqing VIP Information) / 维普网	research/education	commercial

Why These Sources

• Three major state-owned banks (ABC, CCB, PSBC) complement the existing BOC and ICBC entries, completing coverage of China's Big Five commercial banks and adding unique angles: agricultural/rural finance (ABC), housing mortgage and infrastructure finance (CCB), and inclusive finance for rural and low-income populations (PSBC).
• China Life Insurance is China's largest life insurer and one of the most important institutional investors in Chinese capital markets. Its embedded value, premium income, and investment portfolio disclosures are essential references for long-term capital flow analysis.
• VIP (维普网) is the third major Chinese academic literature database, alongside the already-indexed CNKI and Wanfang. Its applied-technology and industry-journal coverage is particularly valuable for engineering and industrial research.
