What were some of the weapons used in the Song Dynasty?

In the Northern Song dynasty (960-1127) gun powder was used in weaponry, the earliest experience in the world. The earliest use of flamethrowers occurred in the Southern Song Dynasty (1127-1279). Powder was held in a thick bamboo tube that spewed flames to burn enemies. During the Snog Dynasty the cross bow was used, it had a long range repeater that had a trigger mechanism, armor-piercing darts, and a range of 200 yards.
