An ability to distinguish between good and poor quality incense materials is far from all that is in a master incense maker's skill set. Sufficient arm power is also important because "swinging the paper fan" taxes one's strength and endurance. Consequently, most incense makers are men.
製香師傅不但要會辨別香料質地，手力也很重要，因為過程中的「掄香扇」相當耗體力，所以製香師傅大多都是男性。
