Dear Mr. Mantak CHIA I'm 62 and live in the Republic of Belarus. I started to be interested Quong - Exercises for a back three years ago. I've been having pain in my knees and back. Traditional medicine to reduce these pains constantly advised to take expensive medicaments. I took them a few months and felt deterioration of liver function and memory. On the Internet I found a video Quong - Exercises for a back, Chi Quong - Deep breath and began to follow them. These exercises have helped me and continue to do them until today. On the Internet, I also found a number of other exercises. I recently learned about your wonderful books and I would like your help to continue my studies. Yours respectfully
