A new brand: the birth of the old man's house
From Yongliang, plus the old man's house, to the old man's house in Yongliang

Coinciding with the period of rapid economic growth in Taiwan, at the beginning, only the Yongliang brand was used to manufacture rock sugar and brown sugar to meet the domestic market, and as rock sugar and brown sugar could no longer meet the ever-changing taste needs, a new brand, “Old Man’s Winter Melon Tea Brick”, was born, which extracted the original taste of winter melon with innovative and improved manufacturing process, and gradually expanded the domestic beverage market. Shouting the old man’s house in authentic Taiwanese means the inheritance of experience and skills, and the honest and simple, hard-working father who supports a family, and this is also the original intention of the “Yongliang” brand: for the people we love. The old man’s family is in Dongshan, Tainan, in addition to supporting his own family, he also silently supports many families, and accompanies them through many life growth journeys, perhaps changing jobs, maybe retiring, or serving for 20 years, this factory has carried many microcosms of life.

With the growth of business volume year by year, and in order to comply with the ever-changing food safety regulations, all the factories of Yongliang Laotoujia have been verified by HACCP and ISO22000 (the earliest in the industry, passed in 2011, 10 years ahead), and all Yongliang sugar and Laotoujia products have also obtained halal certification, and exported to Indonesia, Malaysia, Thailand, Canada, China, the United States, the United Kingdom, the Netherlands and other places, and the demand for Laoman’s winter melon tea bricks in foreign markets has also increased year by year.

The old man’s house in Yongliang is like a sugarcane, such as a straight deep root in Dongshan, Tainan, and wins the favor of customers with our honest service. Yongliang old man’s home is the latest old brand, and whether it is young or old, Yongliang old man’s home only does one thing: we use love and responsibility to eliminate difficulties.
