Qigong is the phonetic transcriptions (Qi and Gong) of two Chinese characters as shown in the title. Qi means literally air, which represents a kind of energy flowing according to certain routes in your body. Gong means the great effort or work put into the qi practise. Through working inside your body and mind, using the methodology of Qigong, you may achieve a perfect harmony in your body, mind, and spirit, so this may lead to a more energetic and healthier life. Therefore, Qigong is the Chinese way of cultivating the human body and is the ancient Chinese methodology for health, therapy, and longevity.

Qigong has a history of at least 3,000 years in China. It is believed that Qigong was gradually developed through the struggle for survival in ancient China. People found that certain body movements along with various ways of breathing and mental concentration, could greatly improve some body functions. These techniques and knowledge were further refined over time and passed down through generations. Qigong often has a strong bond with religions, particularly Taoist and Buddhist. One of the examples of this bond is Shaolin Temple, which is well known for its martial arts or Qigong (Qigong is considered the base of martial arts). Many quite different forms of Qigong were established over the long history of Qigong. The bond between Qigong and religions is an important factor for the many forms of Qigong.

It might actually be Tai Chi Chuan. Tae Chi and other internal Kung Fu styles have a drill that is called stickky hands or push hands where you learn to work balance and also working with your partners balance and energy. It is designed to let someone begin to explore the self defense aspects of the art. I am not an expert on it by any means. Since you say pairs I am assuming thy were in actual contact with each other? Below is a link for you. Hope this helps.

The people you seen were practicing either Bagua zhang or Hsing Yi or Tai Chi Push Hands. Two person drills such as push hands and san sao are used to help the student learn to fight with the art. Tai Chi Chuan when performed correctly is actually one of the most devastating empty handed Martial Arts known to man.

sounds like it could be Aikido
