That helped connect the commune to commune, coming to the suburb of the city, and even to the enemy’s area. Each tunnel system has one main tunnel which is sinuous, rise and fall, high and big enough for a man to walk with a stoop. The tunnels’ roof is often 3 to 4 meter thick, which is able to be under pressured of 100 kg bomb and the 50 ton tank. Around the tunnels are branches to the secret tunnels, which are the living and working places. Among the main tunnel and the branch is the short way but it is very well created. In case one part is discovered, the others will still be safe.
