Can anyone discuss the special characteristics of the Six Harmony Praying Mantis style(Liu He Tang Lang), specifically the Liu He part of it? I know that Hsing-I Chuan(Xingyiquan) also trains the six harmonies, like the hands and feet should move and arrive together, the elbows and knees should move together, and the shoulders and hips should move together. Is the Liu He in Xingyi similar to the Liu He in Six Harmony Praying Mantis? Does anyone know of any websites on Six Harmony/Combinations Praying Mantis Kung Fu?? Thanks!
