The purpose of constructing Great Wall was to defend China from the attacks of the Huns. To facilitate summoning soldiers watch towers and garrison stations were set at regular intervals. The watching soldiers used to send signals to other solders. They used to make beacon fire. It means a massage that there were attacks from outsides. Then, other soldiers quickly want to fight against the enemies from the summit of the wall. #Motivation/Inspiration
