The face is like a bottle... (Zen Tang) and the PHILTRUM... is like the neck of a bottle.
The eyebrows collect chances of luck... before the age of 30... and let it flow into the area through the point of the nose (Zhen Tang). The tip of the nose and the wings act as a reservoir of chances of luck in the middle ages. Then it flows from this reservoir to the mouth (the sea). Through the PHILTRUM.
