Since being in Vietnam, I have learned a lot about the history about the 越南战争 (Vietnam War) from visiting the 非军事区 (De-militarized zone) accompanied by a former combat 翻译 (interpreter) from the time.  When we went to the former border between north and south, he pointed out that the 共产党 (Communist Party) had a 旗杆 (flagpole) as well as a 纪念日 (remembrance day) for the fallen north soldiers, but not those of the south.  The only time we were able to see the flag of the southern Vietnamese army was when we looked at a small picture visible in the 博物馆 (museum).  Many people who took up arms from the south are still on a 黑名单 (blacklist) and neither they nor their children can work for the government.  To learn more about the north, I went with my friend to visit some 隧道 (tunnels) dug by the northern army.  These tunnels were close to the sea, but surprisingly they were able to dig a 水井 (well) holding only fresh water.
