Korean dramas <; Lobbyist > , 24 episodes, the story is about the success or failure of lobbyists who connect with the government and arms dealers, with some knowledge about military weapons.

Korean drama < The war of money > In the 2 episodes, the story tells that fund managers take the road of usury and use their wisdom to help those poor people who are in trouble because of usury.

The two series I recommend are Korean dramas. In fact, the drama of Korean dramas is getting wider and wider, with more than 18-24 episodes, and I think Korean dramas are more concise than those of continental drama, Hong Kong and Taiwan.
