Pingtung County’s Zhutian Township has strong sunshine and good water quality. Because of these advantages, this small Hakka community in southern Taiwan once had dozens of soy sauce factories, but now there are fewer than 10 left.

When he was young, Li An-tian (李安田), known as Uncle Soy Bean Sauce, was one of the few brewing technicians who had received training in the early days. He entered the largest soy sauce factory in the area to learn about brewing techniques as well as how to run a business. But the soy sauce that was brewed at that time tasted too salty. Li An-tian wanted to brew soy sauce in a way that retained the original flavor of soy. So in 1972 he established the "Original Sauce Garden", insisting on following the ancient process of brewing natural pure soy sauce. As a result, he has managed to brew soy sauce that truly belongs to the Taiwanese people under the strong sun of Pingtung’s Zhutian Township. For more than 40 years, he has used the wisdom of the Hakka ancestors in pickling and fermenting, the unique natural brewing resources bestowed by God - the bright sun in southern Taiwan - and the water flowing down from Dawu Mountain, to cultivate soy sauce in the small town of Zhutian, allowing the ancient flavors to continue to be passed on.

Feeling up in age and seeing the market consumption trend changing rapidly, Li successfully handed over his hand-brewed soy sauce business to the second generation of his family. With the concerted efforts of the younger generation, it was determined that the name local people called Mr. Li - "Uncle Soy Bean Sauce" or “Doyoubo” in Mandarin Chinese – would be used as their product’s brand name. They established Doyoubo Industry CO., LTD., and successively introduced the pure brewing process into soy sauce making, and used modern exquisite equipment in the production standardization to ensure that every bottle of soy sauce meets high-quality specifications. In addition to combining ancient brewing methods and natural ingredients, Doyoubo also sends its products for inspection on a regular basis to ensure food safety. It also promotes the exquisiteness of this local product to the world, and has reaped the rewards of its persistence and insistence on quality.

With a strong sense of gratitude and love for this land, Doyoubo collaborates with Taiwanese farmers to select the right beans, land, and season, and uses natural agricultural methods to grow non-toxic, pesticide-free, 100% non-genetically modified soybeans, black beans, and organic wheat to use as the main raw material for brewing. And with a strong sense of responsibility and affection for its hometown, the company insists on brewing the nostalgic taste of soy sauce in Zhutian, Pingtung.
