And so, when the mainland opened farms to drain gall from live bears, the international community at first didn't have much to say about it. But after Taiwan relaxed restrictions on visits to the mainland, suppliers from all over the island crossed the strait to purchase bear gall. To meet a growing market demand, the number of farms grew, as did the attention they were attracting from international conservation groups.
因此，早期大陸發展熊養殖場，抽取引流膽汁使用，國際並未多加置喙，但大陸開放後，各地中藥商紛紛前往購買熊膽，當地熊場因應市場需求，大量增加，國際保育團體的關切也隨之而來。
