Learning chinese ain't easy! It's a tone language and I would advice you to attempt a language course with a teacher who speaks your mother tounge otherwise it's going to be too hard, unfortunately. But I whish you good luck with it, chinese is going to give you good chances in your job cause China will play a leading role in economy in future.
When do you think people die?
When they are shot through the heart by the bullet of a pistol?
No.
When they are ravaged by an incurable disease?
No.
When they drink a soup made from a poisonous mushroom?
No!
It's when... they are forgotten.
