My Way of Wing Chun

I decided to make a graph of the Wing Chun lineage that I follow. But, that is where I stumbled for a moment – what is the lineage that I follow, who is my Sifu? Is it the person whose school I am attending currently, the person who taught me or who has taught me for longest?

I made a decision to acknowledge every Sifu that has ever taught me, regardless of the time length. If a person has tried to teach me something, has passed me some knowledge, a piece of puzzle – he was my Sifu at that moment and I was his student.
