Shigandang

Shigandang (simplified Chinese: 石敢当; traditional Chinese: 石敢當; pinyin: shí gǎn dāng; Wade–Giles: shih-kan-tang; Japanese: 石敢當, romanized: ishigantō) is an ornamental stone tablet with writing,[1] which is used to exorcise evil spirits in east Asia.

Erecting Taishan shi-gan-dang nearby the houses, villages, bridges and roads has a long history in China.

During the Tang dynasty, these three characters have been carved on stones and were used to protect houses from evil things.

However, shi-gan-dang's function has been diversified that it not only prevents people from evil things, but also from wind, water and disasters.
