🏆 Top Rated | ✅ 100% Job Success | 📜 Licensed PRC Attorney | 💬 English / Chinese Sourcing from China works well — until it doesn't. A supplier goes quiet after the deposit, the goods don't match the sample, or your product appears on a competitor's store. I help foreign buyers and brands stay protected: preventing these problems with the right contracts, and resolving them firmly when they've already happened. Clients tell me what they value most is straight advice. I give you an honest read on your position — the strengths and the weaknesses — before you spend money, even when that means telling you a matter isn't worth pursuing. No overpromising. Clear communication. Everything in writing, so it holds up under Chinese law. 🛡️ China NNN Agreements & Anti-Circumvention Protection ✅ China-enforceable NNN agreements (non-disclosure, non-use, non-circumvention) ✅ Protection against factory copying, supplier circumvention, and subcontractor leakage ✅ Trading-company NNNs with flow-down obligations to the underlying factory ✅ Customer relationship and channel protection clauses 🏭 Manufacturing, OEM / ODM & Supply Contracts ✅ Manufacturing, OEM, ODM, supply, and vendor agreements ✅ Tooling and mold ownership; quality, inspection, and acceptance terms ✅ Payment milestones, delivery, and liability allocation ✅ Distribution and licensing agreements 🔍 Counterparty Due Diligence ✅ Background review of Chinese suppliers and manufacturers ✅ Registration, shareholder, and capital structure (registered vs paid-in) ✅ Litigation, enforcement, and credit risk records ✅ Payment-entity mismatch and affiliated-company review ⚖️ Supplier Disputes, Demand Letters & Pre-Litigation Strategy ✅ Supplier and payment disputes under PRC law ✅ Chinese-language demand letters sent to the registered Chinese address ✅ Evidence review, settlement strategy, and debt recovery support ✅ Freight forwarding and cargo disputes (delay, loss, telex release, demurrage) 🏷️ China Trademark & IP Protection ✅ China trademark registration and filing strategy (first-to-file) ✅ Bad-faith trademark response and opposition ✅ Design patent and trade-secret protection ✅ Product, packaging, and commercial asset protection 🌐 Cross-Border Dispute Support ✅ China-side support for cross-border arbitration and litigation ✅ Coordination with foreign counsel; evidence and fact work on the China side ✅ Settlement and defense strategy support 🏢 China Market Entry & Corporate Structure ✅ Market-entry and corporate structure review for foreign buyers ✅ WFOE / representative office considerations ✅ Pre-JV and strategic cooperation structuring 🤝 How I Work ✅ Bilingual delivery in English and Chinese where it strengthens enforceability in China. ✅ Mainly in writing, so you keep a clear record of advice, instructions, and decisions. ✅ Typical response time: under 1 hour.

China-based Treatment Intelligence Analyst and Independent Patient Advocate, specializing in oncology and rare disease. I help biopharma, investment, and market research firms track Chinese drug pipelines, companies, KOLs, and clinical trials using local sources that don't surface in English-language tools. With an M.Sc. in Medical Genetics and 10 years across precision oncology, genomic interpretation, and corporate due diligence, my core skill is one thing: using OSINT and a real medical background to find verifiable, hard-to-reach information where the data is fragmented, gated, or simply not public. I work with two kinds of clients. -For companies and investors: --China biopharma competitive intelligence — pipeline tracking (preclinical to Phase III) across NMPA, CDE, and ChiCTR; company profiles, funding rounds, partnerships, and regulatory updates. --Global biopharma lead generation — finding target accounts, verifying decision-maker emails, and building source-linked contact lists. --China corporate due diligence — public-record verification through Qichacha, Tianyancha, and NMPA filings for investors running early-stage screening before they commit to a full background-check firm. --KOL and medical-influencer sourcing, plus WeChat / RED monitoring that overseas researchers can't access directly. -For individuals facing rare, genetic, or advanced disease: --I act as an Independent Medical and Treatment Intelligence researcher, not a doctor. I take your case details, genomic/NGS reports, and history, and conduct a global search for clinical trials, off-label options, and emerging therapeutic approaches — including clinical trials and FDA-approved drugs that rarely surface in databases. --I deliver a structured Treatment Intelligence Report with prioritized options and source links, so you can take it to your treating physician and decide together. The medical decision always stays with you and your doctor. Why clients come back: Chinese biopharma data is often incomplete or contradictory. I know where it lives, when to trust it, and when to tell you plainly that it simply isn't public — no guesswork, no padding. All completed projects got all 5-star. Fluent English. Based in Hangzhou, fully available for UK / US business hours.
