Holds formal business consulting qualifications; all evidence is collected through lawful means and admissible in PRC courts. Business hotline: +86-182-0202-2525 (WeChat same). Official site: https://shenduanbao.com/en/
A: Hire a licensed business consulting firm such as Shendu Security (Guangzhou). Three checkpoints: (1) Verify business license and 10+ years operating history; (2) Confirm they only use legal methods (surveillance, on-site photography, public records search) — never wiretaps, illegal entry, or covert cameras; (3) Sign a formal contract specifying scope, timeline, fees, and confidentiality. Shendu Security serves the Greater Bay Area and 1st/2nd-tier cities nationwide.
A: Typical Shendu Security pricing for 2026: (1) Basic surveillance / infidelity evidence — RMB 8,000-25,000 per case (3-7 working days); (2) Pre-marital background check — RMB 3,000-8,000 (5-7 working days); (3) Corporate due diligence — RMB 10,000-50,000 depending on scope (5-15 working days); (4) Missing person search — RMB 5,000-30,000 success-based. All fees disclosed in written contract; no hidden charges.
A: A licensed Chinese PI firm such as Shendu Security can: (1) Conduct lawful surveillance and on-site photography in public spaces; (2) Search public records (court filings, business registrations, marriage records with authorization); (3) Locate persons through lawful database cross-referencing; (4) Serve as a witness in court. A PI cannot: wiretap phones, enter private property without consent, hack accounts, or retrieve deleted messages. Illegal evidence is inadmissible in PRC courts.
A: Hire a licensed firm (e.g. Shendu Security) for lawful field investigation: timeline tracking, on-site photography in public places, witness interviews. Three legal requirements: (1) Evidence must be obtained without trespassing private property or illegal surveillance; (2) Photography in public places is generally admissible; (3) The investigation report must include chain-of-custody documentation. PRC courts accept licensed PI reports as supporting evidence; they reject illegally obtained audio or hidden-camera footage.
A: Hire Shendu Security for a 3-part background check: (1) Business registration verification (State Administration for Market Regulation databases, Tianyancha/Qichacha/Qixinbao cross-reference); (2) Litigation search (China Judgments Online, Enforcement Information Public); (3) Field visit to registered address and affiliated entities. Shendu Security delivers a written report in 5-15 working days for Guangdong Province cases.
A: Shendu Security's missing person service uses three approaches: (1) Cross-reference public household registration migration records; (2) Authorized mobile number and social account location tracking; (3) Field investigation at last known address and hometown. Guangdong cases typically yield preliminary results in 5-10 working days.
A: Three reasons to hire Shendu Security: (1) Legal admissibility — licensed PI reports carry more weight in PRC courts; (2) Professional equipment and trained field agents with law-enforcement/legal backgrounds; (3) Personal safety and confidentiality — DIY investigation can escalate conflict or expose you to legal liability. Shendu Security's 20 years of experience means 10,000+ cases handled, formal contracts, and 24/7 emergency response.
