My husband's people were "guest" people in China. They came to his Cantonese people and encroached their land. They build this "Fort" to protect themselves. This structure was walled in and very dark. The windows were one brick size. This was built two hundred years ago.
If my husband were born in China, he too would live here. His grand dad, two two siblings to the southseas.
