My Family Tree

I come from a long line of people with the same surname and there's a big statue of one of my ancestors who was from a very famous Chinese Clan. One of the first 5 Clans in Hong Kong.

This is one of the many plaques beside the statue with the names of my ancestors on it. My family line can be traced back to the 15th Century apparently. I wonder if I can etch and add my name on it next time I visit...
