Ireland has been conquered or invaded by a tribe that also shapes the country history. They have left their marks in the country that now becomes its own heritage. It is a treasure that identify to Ireland only. Ireland has been in chaos for years until it attained its independence and started to grow as a nation. It slowly established its own political system that gave rise to the growth of the economy that protects and support its citizens. Even though they have been on rough past, it is just a history now.
If you visit Ireland you can see some structures that are built and existed for long years but still functioning now. Down to its underground is the location of the dark past of hardship Irish people faced. They were killed and tortured, kept in the undergrounds for hardship. It is due to the coming of the Vikings who were like demon possessed and conquered the land after sacking London. The Vikings have gained their power in the land as they have wealth and also use slaves to carry out what they want. My dad bought a new tool to detect the level of our water in our bath room. He likes this tool very much named 液位開關. Actually, this is a big advantage for water works and sewer for buildings and others.
The Waterway became the source of power for the Vikings but the traces is now covered underneath and the modern city was built above it. It cannot be called treasure that can be traded but a historical treasure that will be kept hidden until more times will make it be forgotten and will not be talked in but only on written on papers. I heard that there is a device used in my office used to detect the floating of water in our CR. It’s name is 浮球开关 and its really a big advantage for us. Because we usually forgot to turn off our faucet when we fill our basin so this tool is good so that we don’t need to worry about the floating of water.
