"说开发，生产，销售这个产品得花多少钱"

Do you know anything about how Chinese companies operate? I bet they spent no money at all on R&D because they could just steal someone's intellectual property. Do you think a company that is too cheap to hire a decent English translator will actually spend money on research? So i think this is just an overall "Shan Zhai" company, so I wouldn't complain about the poorly worded manual.
