## About

Dou Zhenggang established Jin-Jiang Chemical Dyestuff in 1991 as part of the broader Hangzhou Jinjiang Group, a privately held Chinese conglomerate with roots in textile dyes and environmental-chemical production. The group has since expanded into energy and real estate, with Dou, his spouse Wei Xuefeng, and daughter Dou Baibing holding overlapping ownership stakes across the group's entities. Hangzhou Jinjiang Group remains the primary operating vehicle, with Jin-Jiang Chemical Dyestuff serving as the core production unit for green and environment-friendly chemical products. Jin-Jiang Chemical Dyestuff's direct investment posture is functionally a corporate venture and real-asset allocation program funded by retained earnings from its chemical-manufacturing operations. The known portfolio is concentrated in commercial real estate in Hangzhou's West Lake District, anchored by the Diamond Office Building at 1108 ZhiJiang Road. A mixed-use rental portfolio in Hangzhou, Zhejiang, completes the domestic real-estate book. Team composition and total deployment figures remain opaque, consistent with a privately held Zhejiang industrial group. The German subsidiary adds a second geographic node, though its scale and headcount are unreported. No philanthropic foundations, club memberships, or third-party fund vehicles are publicly associated with the family. Jin-Jiang Chemical Dyestuff is structurally a family-controlled industrial company that reinvests operating profits into hard assets — a pattern typical of Chinese industrial families but distinct for its direct European manufacturing beachhead. Unlike single-family offices that have separated investment activity from the underlying operating business, the Dou family's capital allocation remains embedded within the Hangzhou Jinjiang Group corporate structure, with no evidence of a standalone family-office entity. This blurred line between operating company and investment vehicle makes external co-investment unlikely and sourcing entirely self-generated.

## Questions

### What is the firm's known investment asset mix?

The known investment portfolio is limited to commercial real estate in Hangzhou's West Lake District, anchored by the Diamond Office Building, and a mixed-use rental portfolio in Hangzhou, Zhejiang. The 2008 German subsidiary represents an operational rather than purely financial investment. No fund commitments, venture positions, or financial-asset portfolios have been publicly identified.

### Does the firm participate in fund commitments or only direct deals?

Based on public records, Jin-Jiang Chemical Dyestuff and the broader Hangzhou Jinjiang Group appear to invest exclusively through direct ownership — both in operating subsidiaries such as the German chemical unit and in physical real estate. No fund-of-fund commitments, GP stakes, or third-party managed vehicles have been disclosed.
