Chen Huan-tang states that it is relatively easy to make distinctions among lightly cured teas because the flavor is relatively "clean" and distinct. But more strongly cured teas have a deep smokey flavor, so it is by no means easy to make such incredibly refined distinctions.
陳煥堂表示，這在輕焙火茶還容易掌握，對焙火較重、香氣較沈的茶葉時，要作如此細微的分辨，就不容易了。
