Chen Kuo-renn, head of the tea manufacturing section of the Tea Research and Extension Station, says that unlike high-mountain oolongs, which are wrapped into relatively rugged little balls, Wenshan pouchong tealeaves are long, fragile and difficult to transport. As a consequence, teas of this type are less frequently imported, and less frequently passed off as Taiwanese teas.
桃園茶業改良場製茶課長陳國任則指出，不同於包裹成球形、面積小、不易碎的高山烏龍茶，文山包種茶的條狀茶形一壓就碎，不利運輸進口，比較沒有進口茶混充台灣茶的問題。
