In the 6th grade, I went to the Cu Chi Tunnels, where the Southern soldiers successfully defended themselves in fierce battles. Now it has become a place to visit for tourists, there are places to sell souvenirs, live ammunition shooting range, paintball shooting. There are tunnels that go underground very later and are dangerous for the enemy to enter. There are also teaching classes down there, guns, planes, tanks, cannons,... Currently being maintained and repaired to decorate the place. I hope to be able to return there one day soon and see if it develops more than when I first came.
