Teacher Han Tiannuan is the founder of Beijing Nima Yoga, among which meditation classes and meditation hypnosis classes are very popular. In the theme hypnosis class, most students can easily see their past lives and future.

In 2009, a yoga hypnosis method called "Up and Down Lotus Breathing Method" was originally compiled, which was very useful. At present, many of his students have applied this method to yoga teaching, and replaced the original yoga relaxation technique with "upper and lower lotus breathing". That year, a doctor from a military hospital made a special trip to study it for clinical treatment of insomnia, and the effect was immediate.
