About Yang Squared
Yang Squared is the export-facing brand operated by 深圳市坪山区百辛源贸易商行（个体工商户）. It brings generations of family market experience into a modern service for clearer international buyer communication.
A family route through trade
Yang Squared is a new export-facing business, but the instinct behind it comes from a family history of connecting products, people and regional markets.
From the 1980s
Gansu ↔ Shaanxi
Our story begins with Fu’s grandfather, who joined the first wave of private commerce that followed China’s reform era. He traded traditional medicinal materials and seasonings between Gansu and Shaanxi, learning that reliable business depends on knowing the product, the market and the person across the table.
From the 2000s
Xi’an
Members of the next generation established their own individual businesses in Xi’an and continued this work into the present day. Relationships, direct conversations and practical market judgement remained at the centre of the business.
Today
Yulin → International markets
Markets are now faster and more digital, yet buyers and merchants still lose time through fragmented information, language gaps and unclear requirements. AI changes how information can be organised; it does not replace trust or verification. Yang Squared brings both together.
Why Yang Squared
Yang Squared represents continuity and progress: inherited trading knowledge combined with structured buyer briefs, clearer product information and modern communication. We are not claiming generations of export history. We are building a new international service on generations of market experience.
