How to say "make money"? I'm trying to say "the Song Dynasty used this invention to make paper money". So far I've got "宋朝用了这个发明做纸钱“。 The "make money" part is messing with me- I know "做钱“ can mean to print counterfeit money, and I'm not trying to express that. I also know the word "赚钱”, but I know that's to earn money in a job, not to print it. And does the word "纸钱“ effectively express the idea of paper money, like bills, or does it just sound strange? 

Also, the simplest word would be best! :)

My research: 

I've plugged "make money" into various online translators, and either gotten "赚钱" or "做钱", hence the question. 
For "paper money", I've gotten "纸币" and "纸钱“, neither of which I'm totally sure of.
生产纸币: to manufacture paper money/ to produce paper money
制造纸币: to make paper money / to produce paper money
发行纸币: to issue paper money
印制纸币: to print paper money

It should be 宋朝用这个发明来制造纸币 (来= to)- Song Dynasty used this invention to make paper money
'做' means 'being', it should be '制造'(make)

Note the difference between 制造 and 制作 Difference between 製作 and 製造?
