When was the first gunpowder-propelled rocket made and how was it used?

The first rocket propelled by gunpowder was made in A.D. 1000 by Tang Fu, the captain of Shenwei in the Song Dynasty. The use method is: ignite the gunpowder in the bamboo tube, make it burn, generate thrust, make the rocket fly to the enemy line, and then the gunpowder carried on the arrow explodes and burns again, killing the enemy. Soon, Shipu, the ambassador of Jizhou, also made rockets, fireballs and other firearms and performed them.
