Southern Song (1 janv. 1127 – 1 janv. 1279)

Description:

Time period after Song retreats south, leaving central and northern China. Song doesn't have to pay as many annual payments, and makes many advances in technology, medicine and astronomy (fractions, precise calendar, sea-worthy compasses, and stern mounted rudders for junks). Metallurgy reaches all time high. Also, gunpowder!
