The two key elements in our body of Chinese theory

Mentioning about Yin and Yang (陰陽 {Cantonese pronunciation: jam1 joeng4}), must talk about Chi and Blood (氣血 {Cantonese pronunciation: hei3 hyut3}). They are the key elements in our body of Chinese theory. “Chi” (氣) is Yang while “Blood” (血) is Yin. “Chi” acts like a sun in our body. It gives us warmth. “Blood” acts like water in our body. It moistens our body.

To elaborate the meaning from the word:

氣 is combination of气 + 米. 气 is air current or airstream within the Mother Earth;
米 is rice from the word basically. It represents foods, moving reaction of stomach and guts / digestion.

So “Chi” (氣) means air, gas, steam, vapour or spirit that created in body after digesting foods.

血 is combination of 丿+ 皿.丿 is a drop of liquid;皿 is a shallow container;

血 is drop of warm and red animal blood in container for worship. It extends in meaning for blood nowadays.

By the way we say the word in sequence, we always say Chi then Blood (氣血) but not reversed Blood then Chi (血氣). So basically “Chi” (氣) is a bit more important than “Blood” (血) because “Blood” (血) needs “Chi” (氣) to move it. It is no use having blood alone in our body as it would not move itself.
