Qi is an abstract thing, and you will feel the existence of Qi through some practice methods. But "Qi" is only an intentional process for martial arts practitioners to practice without a sense of Qi at the primary level. Imagine where an airflow passes and stops!

My personal experience and feeling of practicing for a year is nothing more than the feeling that my hands are a little hot when I come to practice martial arts. You'll feel more comfortable after practice, that's all! I practice Tai Ji Chuan.
