Hey im also doing a project in school with my friends. Its and advertisment thing. we already have our company name. Is it about timetravel? Well mine is. Well i could give you a name but i dont know what the project is fully about.

A few great achievements in the Song Dynasty

(1)Progenitors of gunpowder warfare. These guys were scarey. The Song military were using grenades,firearms, cannons and land mines when guys in Europe were all so busy lancing each other.

(2)Inventors of movable type print. These guys read a lot, mass production of books is a must to meet supply.

(3)Inventors of paper currency. Lugging around all those copper coins is pretty lethal work when dealing with large transactions.
