You can be European or Chinese, you may have been born 20 years ago or in 1945, you can call yourself a beginner or a “grandmaster”, but if your advanced position is unnaturally low, your hip is open and your back foot points out, you didn’t understood a bit of Hung Kuen (and IMHO of martial arts in general).
If your front stance looks like the one shown above, why don’t you read this?
You could also take a look at the following image: it has nothing to do with Hung Kuen, it’s taiji, but the principles are the same (thanks Wong Yuen-Ming for sharing it).
