同珍 (Tung Chun/Tung Jen): Hong Kong's Legacy Sauce Master

Brand Identity: Hong Kong's Century-Old Pantry Staple

同珍 (pronounced "Tung Chun" in Cantonese, "Tong Zhen" in Mandarin) is a venerable Hong Kong sauce and condiment brand founded in 1903, making it over 120 years old. While sometimes confused with vinegar-focused Tung Chun from Zhejiang, 同珍 is distinctly Hong Kong—famous for its soy sauces, oyster sauce, and particularly its iconic "sweet vinegar" used for traditional postpartum dishes.
