but Buk Sing has their right to claim the things they've developed. If no one else had developed it before, then they have the right to claim the first.

The Lien Wan Chop Choy is Tam Sam's development, now i see it in Chan Family material. As long as that gets acknowledged by the Chan, and give full credit to Tam Sam, or any school that adopts the Lien Wan into their curriculum, we all need to give Tam Sam full credit.

However, Chan Heung, and Jeung Hung Sing were equally as famous, and Jeung Yim was referred to as one of southern China's greatest fighters, and they deserve full credit for what they developed as well.

We should give ALL 3 masters full credit for what CLF has become today.
