寶安縣
The ancestors of the people of Kau Tam Tso Village first came to settle in the New Territories of Hong Kong during the middle of the Qing dynasty. They were nomadic farmers, planting rice and crops, and moved from one part of the New Territories to another before finally settling down in its current location towards the end of the Qing dynasty. Prior to migrating southward to the New Territories, they previously settled in the Bao'an County at the beginning of the Qing dynasty.
