What is that?

So you are saying that I'm not a chi-maniac yet. Oxygen is the postnatal chi that substain the prenatal chi inside your body.

Ofc Chi is not oxygen., but oxygen is a form of Chi. We have all kinds of chi in the air(空气）. Air is 气, chi. Oxygen is 氧气 in space, 空气!

I don't know what you meant by that. Oxygen can just run into your nose!

IMHO Ginna is good to be applied on an unskilled fighter.

First of all, we must understand the diagram of heel and umbilical breathing, 踵蒂吸呼圖. It show two paths of Chi flow. The front path is 通蒂(umbilical passage ) and the back is 通踵(heel passage). Neidan is the emphasis on breathing. Without breathing, nothing works in Neidan. Breathing is analogous to fire in (外丹)Weidan 踵蒂吸呼 is heel and umbilical breathing. It was assumed that the breath(气) is flowing through the two virtual passages during Neidan meditation. Sometimes, we can't rely on Google translation too much. The proper Taoist term for the method of Neidan is 內丹術. Neidan(內丹) by itself is internal(內) pill(丹); AKA elixir, golden pill; golden elixir; Xin Dan(仙丹) AKA Immortal pill. The names are the same pertaining to the method of Neidan. The breathing to the heels or to the "bubbling spring" in Tai Chi, but not heel-to-toe breathing in Neidan. I wouldn't pay too much attention to those term. They are just some made up names to please the English speaker.

I wouldn't do that if I were you. You will die sooner than you think if follow the above procedure. The brain use 20% of the total oxygen in the body. If the brain is in the hypoxia condition for more than 6 minutes, then it will be brain dead.

This is not true, it means they did not use the lungs in its full capacity. The Taoist found a breathing method to use the lungs more efficient to its full capacity. The breathing method is called 吐納(Tu Na). I don't know have you ever heard of. Nowadays, it is called 氣功(Qigong).

People understand normal breathing not under medical treatment oxidative stress will not happen. Nature only allow for the lungs to be filled with its full capacity. There is no chance for the lungs to overfilled. However, a ventilator is a high-pressure machine used when a patient cannot breathe sufficiently on their own. It physically pushes oxygen-rich air into the lungs may cause Oxygen Toxicity. Oxygen Toxicity: While oxygen is necessary, breathing pure (100%) oxygen for too long can actually damage the delicate lining of the lungs. A few more percentage of oxygen in our lungs, we all die. It is not in the atmosphere. Please keep the fact straight.

I agree. That is general knowledge to distinguish Peng from Ginna. The combination of both can be used but Peng was acquired from Taiji practice before the Ginna training.

Moved to another thread.

Those who think that they know all about Neidan. If they don't know what 踵蒂吸呼 means, Sorry, they don't know what Neidan is all about!

In that case, human biological power(ATP) is from 氧气, oxygen. Let's point a finger to chi, not the moon yet.

We can start with three kinds of Chi, 炁, 氣 and 气. Can you tell the difference? What is 炁(chi) in TCM? What is 氣(chi) to a Taoist? What is 气(chi) to a Qigong practitioner?

Please specify what kind of Chi are you talking about?
