No matter where you look, football(1) is all around you. Athletes(2) like David Beckham, Ronaldo, and Zidane are now household names. But how did this sport come into existence? There is scientific evidence that the Chinese military played a kicking game called Tsu'Chu during the Han Dynasty. In these exercises, soldiers would try to kick a leather(3) ball through an opening(4) that was only 30-40 cm wide. This game has now evolved into the most popular sport in the world.
