Erecting shigandang near houses, villages, bridges and roads has a long history in China. The phrase shigandang first appeared in the Western Han dynasty. During the Tang dynasty, these three characters were carved on stones and were used to protect houses from evil until the Song dynasty Taishan shigandang () appeared. It became widely popular throughout the country to set up shigandang or Taishan shigandang near villages and houses. Furthermore, the custom also spread to the Han cultural sphere overseas.
