How was this profile built — can I trust it?

Yes — it is compiled independently by our AI from dated, public evidence: business registries (via grok), an automated website audit, and Zhejiang Tianyan Holding Co., Ltd.'s own site — not from anything the company submitted. Where Zhejiang Tianyan Holding Co., Ltd. states something about itself, we show it beside the public record, so you are reading sourced facts, not marketing.
