Zhi Qin (David) was born and grew up in a TCM (Traditional Chinese Medicine) family. His father Gansun Liu was one of the best traditional Chinese medicine practitioners in their home town. David learnt about many herbs and acupuncture techniques from his father over the years. One thing that inspired him was witnessing his father helping many patients. Some of them had tried various treatments in the hospitals and were told that the problems could not be solved before they came to acupuncture.
