Hi, I'm Yang Maojuan Dàshū.

Hello from 羊毛卷大叔

I'm Yang Maojuan Dàshū (羊毛卷大叔), a software developer, parent, and independent project builder based in China.

I build practical software around real workflows and keep the product scope focused. PDFLP started from a simple observation: a PDF can contain valuable expertise, but the download itself rarely creates a useful conversation.

Why PDFLP exists

PDFs are still how many teams package expertise, proposals and research. A raw file captures the content but loses the context around it and usually ends with a download.

PDFLP adds a mobile reading layer, a controlled next action and a way to understand whether the document produced a useful response.

Who it is for

• B2B marketers publishing reports, guides and sales enablement content.
• Consultants sending proposals, audits and research.
• Course creators offering previews and downloadable material.
• Small teams that need a focused PDF workflow without a full content platform.

Product principles

• Make privacy and public visibility separate settings.
• Use visible, factual content instead of hidden SEO tricks.
• Keep analytics understandable and acknowledge attribution limits.
• Prefer a reliable first-party workflow over opaque integrations.
• Publish only claims that match the current implementation.
