Through the unique collaboration of the father and son, they have transformed Chinese medicine into a contemporary wellness trend, going beyond just herbal remedies. They aim to carry on the legacy of herbal culture while integrating the local memories of Keelung, ultimately developing representative local souvenirs that embody the essence of Keelung's tourism industry.
