The tour was changed from Japanese to English the day before. The Cu Chi Tunnel was a very good tour. There was a detailed explanation of the traps at each location. I had heard on another tour that it was difficult to go all the way through the tunnel because it was narrow, so I left from the exit one step before. I wondered what would happen when I entered the second basement floor, but the guide was waiting for me near the exit, and it was a very good experience. As I walked through the narrow tunnel, thinking about what they were thinking when they made this tunnel and what they were thinking when they were inside the tunnel, tears came to my eyes. I vowed to protect peace. I did not do the optional shooting, but if you have the courage, I think it is better to experience the three options of shooting + 100m of Cu Chi Tunnel + entering the hole in the dead leaf cover. (About 5 people in a tour of 25 people were experiencing it) I applied for the Japanese tour because I wanted to see it well while studying history, but the Japanese tour was canceled the day before due to a lack of participants. I received a notification on LINE and was asked whether I wanted to join the English tour at the same price or pay the difference for a private tour. A private tour seemed quite expensive, so I arranged an English tour. Information about the meeting place for the alternative tour was slow to come, so I inquired before going to bed at night, and they immediately confirmed the alternative tour and contacted me with the meeting time and the name of the tour guide. The response to my questions and inquiries was very quick, which was very helpful. The English tour is a large group trip, and there are many other tour participants at the site, so it is necessary to remember the guide in charge and to listen and understand the precautions and meeting time in English each time. I think it is a good thing that people from all over the world go to the Cu Chi Tunnels and think about war and peace.
