A small country: President Qin, we’d like to import a batch of steel pipes and gas cylinders! Qin Feng: Sure. The instruction manual includes a structural diagram strictly prohibiting welding the two together!

A client: President Qin, we’d like to purchase a batch of fire suppression compression cannons! Qin Feng: No problem. The manual strictly forbids replacing the CO₂ hollow shells with thermite!

Subordinate: President Qin, we’ve bought back the Minsk! Qin Feng: Good. Proceed with the planned modifications—equip it with various types of drones. Our mission is to observe weather, hydrology, fish schools, etc. We’re converting it into a marine science research vessel!

Alternate title of the book: Sorry, We Really Only Produce Civilian Goods!
