What is the Wannian Chong in Feng Shui?
I don’t know whether you are talking about the annual conflict or the ten thousand year conflict. I have never heard of Wannian Chong, and I don’t know where you heard such a term. In order to scare people, some earth masters always use very illogical words to scare people. A client of mine had a rural Feng Shui master look at their house and said that the compass guide for their house did not point to north. Vulgar remarks like this also appeared. .
Simple annual conflict, for example, this year's Jiawu year, a house with Zi to Wu will be a year conflict, because Ziwu is opposite. If there is an annual opposition in any year, then your house will rotate 15 degrees every year. This is an incredible thing, unless your house is suspended in space.
