As tea planting and trading were the economic life blood of the Tataocheng district, Governor Liu helped traders to organize an association to promote the industry further and set up standards of conduct.
劉銘傳經營台北時，眼見茶葉對民生有厚利，倡設「永和興茶郊」，透過大稻埕茶商的結社，一方面謀求茶業的發展，一方面也樹立台灣茶業的商譽。在他的銳意推動下，茶業在大稻埕更是蒸蒸日上，此後這一帶的茶商便執台灣茶出口的牛耳。
