Lao Chang Sheng was born in Keelung and has been cultivating natural Chinese medicine, where traditional medicinal materials are available and serving people through his traditional medicine store for many years. However, over time traditional Chinese medicine has gradually declined and Lao based on his father's Chinese medicine profession and the food expertise of four generations, adopted a new focus. Starting from the development of health-preserving dietary products, father and son have integrated with different industries to make traditional Chinese medicine more popular and a modern health food trend. The store operator looks forward to continuing the traditional herbal culture combined with Keelung local memories, and developing representative local tourist gifts.
