Master Feng Shui, please come in.

Shi Gandang is a relic of the worship of ancient lingshi. He hates disasters and avoids evil spirits, and has nothing to do with "people". The language of "Shi Gan Dang" in the historical tour of Jizhang in the Western Han Dynasty should be interpreted as a stone that can be used to fight against everything. Later, whether it was the inscription unearthed in Putian in the Tang Dynasty or the stone of "Shi Gandang" planted (or buried) at the bridgehead or in front of the house, its meaning was the same. As for the addition of Mount Tai (namely Mount Tai Shi Gandang) before Shi Gandang, it started in the Ming Dynasty and prevailed in the Qing Dynasty. Today, it means to use the sacred Mount Tai to increase Shi Gandang's strength. In the same way, "Sun Moon Stone Dare to Block" is the name given by modern commercial speculation, so don't worry about it.
