Why is the name Taishan written on Ka Kui Wong's tombstone?

Hello, because most Hong Kong people moved from all parts of Guangdong in the past, not from Hong Kong, so they will indicate their ancestral home.

Jiaju's ancestral home is in Taishan, Guangdong, so it is indicated on the tombstone. I saw that the cemetery where A lived was marked on tombstones in other places, not Hong Kong.

Thank you.
