A huge influence on the modern world we live in today is the song dynasty from inventions such as gunpowder, porcelain, creative work, and the compass. Obviously gunpowder is now the basis of many weaponry such as guns, canons and bombs, so in theory without the Song dynasty wars in america might have played out differently. Porcelain is used for many dinner ware that we use today ,but we now know it as china (get it). Creative works such as art and writings help our modern world understand Chinese history through writing as well as innovate art from the past and now modern artist still use the styles today. One of the biggest modern influences is the compass, without the compass we wouldn't, have the gps and without the gps we would have a bunch of people going places they didn't know where they were going. All in all without innovations from the song dynasty the way we would live our life today would be changed drastically.
