From the outside they look very alike. People moving their arms slowly and attentively, mostly on the spot, without music and without speed. Plenty of people use the words interchangeably. They are not interchangeable.
The difference is not in the tempo or the appearance but in what each of them is for.
What Tai Chi is
Tai Chi - properly Taijiquan - is a martial art. Every movement in it has a martial meaning: a deflection, a taking of balance, a strike or a throw, simply performed very slowly. The slowness is not an aesthetic choice but a teaching method - at that tempo every fault in the structure shows, where speed would hide it.
The content of Tai Chi is a form: a long, precisely defined sequence learned over months or years. A classical long form runs to well over a hundred movements. Alongside it there is partner work, and in traditional schools weapons and sparring too.
In practice this means the first year of Tai Chi is largely learning a sequence. Some people find that appealing and others find it frustrating.
What Qi Gong is
Qi Gong is not a martial art and does not pretend to be. It is a health and breathing practice - a system of exercises for breath, mobility, posture and settling, which existed in Chinese tradition long before any martial school.
The content of Qi Gong is individual exercises, not long sequences. Each one is complete in itself, lasts a minute or two, and is repeated several times. The best known set, the Eight Brocades, has eight exercises and can be learned in a few months - not because it is shallow, but because it is designed to be useful from the start.
That is the biggest practical difference: in Qi Gong you are doing something useful in the first hour. In Tai Chi the first year is mostly learning what comes after what.
What they share
A good deal. Both come from the same tradition, both rest on slow movement matched to breath, both require relaxed structure, and both work on balance and posture. Tai Chi contains Qi Gong elements - in any serious school the warm-up and breathing exercises come straight out of it.
For someone looking for calm training without impact loading, both are good answers. Which makes the question of “which” less momentous than it seems.
Which to choose
Choose Qi Gong if you want exercises you can do at home within a month. If learning a long sequence does not appeal. If your reason for training is your back, your breath, your sleep or stress. Or if your time is limited and you cannot guarantee two years of regular attendance.
Choose Tai Chi if you are interested in a martial art and not only a practice. If long, precise work on a single thing suits you. Or if you already have martial arts experience and want the slow, internal side of it.
If you cannot decide, Qi Gong is almost always the easier entry for a beginner. Moving from it into Tai Chi later is straightforward; the reverse is harder, because Tai Chi asks for a patience people usually only acquire through training.
What we teach
We teach Qi Gong, not Tai Chi. The reason is simple: Qi Gong stands beside Kung Fu as a complement, not as a second martial art. Kung Fu builds structure and strength, Qi Gong breath and release, and it is that combination that works in our hall.
Anyone looking for Tai Chi will be told honestly that they will not find it here. Anyone who does not know which of the two they actually want usually knows after one Qi Gong class.
