Send three strangers — people who have never met — to a physical address in China (factory, shop, or office) on different days, unannounced. Each photographs the storefront, asks one question inside, and writes down what they saw in their own words. You get all three accounts in one report. Use this when the question is "does this supplier actually exist / is it actually operating / does the sign match the address" — things only someone standing there can answer. Charges the account balance. 派三个互不相识的真人去中国境内的某个实际地点（工厂、门店、公司办公地）实地核实，拍门头照、进店问一句、各自独立写下判断，出一份报告。适合回答"这家供应商是不是真的存在/真的在营业/招牌和地址对不对得上"这类只有到过现场的人才知道的问题。下单会从账户余额扣款。
