offshore company

Offshore company why is headquartered in the sea? This is a question I asked brother student, I don’t know, like this, my brother told a whole hour to him, from the offshore company to offshore tax planning, and later from home chore emotion metaphor, finally returned to offshore company. Offshore company quite strange to me, are elected for my family, they don’t know what to say, I don’t want to know what it is, but they know that they don’t understand something to the brother many things that others do not. What they don’t ask offshore company, seemed to hear very input
