offshore tax planning

The first contact offshore company is in my university time, at that time, because of the school’s international trade for the offshore tax planning must master, at that time I also think this kind of thing is not necessary to master, as long as they know what is good, so when it is of no use great effort to study. Until I work later how stupid I know I had the idea, because of my company now is a foreign trade company, everyday the thing so in order to be able to very good. So every night I go home to cram, now I think I really regret, if I study hard will not appear this kind of problem.
