Now, I'm practicing a very simple one under no instruction. It’s not hard to learn but very hard to persevere in.
After several months of exercising, I started to see the effects. The severe acid reflux is gone and I can eat more , sleep more and feel more energetic. I stopped all medicines, stomach pills, sleeping pills and vitamins. My blood pressure becomes normal ( I used to have low blood pressure). I feel very grateful that our ancestors passed this wonderful QiGong to us.
