i went to cu chi tunnels in vietnam today. after going here, i felt it was really interesting to go back to history and learn more about it...
anyway, cu chi tunnels are tunnels built by the cu chi guerillas during the resistance war with US. cu chi guerillas, brought about by hate for the americans (because they saw their parents and relatives killed at a very young age) made traps, tunnels, etc in this area and it was a real clever military tactics!
entered a 20m tunnel... and i'm telling you, it was so claustrophobic!!! it was even adjusted already so it can fit westerners! but it was still so small! and before... there were even no lights inside this tunnel. it was really amazing...
here's a snapshot on the entrance...
