The Yicihui Stone Pillar stands at Shizhucun in Dingxing County and dates from the Northern Qi; it is about seven metres tall and carries more than four thousand characters of inscription. The octagonal pillar is thick in the middle and tapers toward both ends, a form called the fusiform column, and it carries a three-bay stone hall on top, a precious model of the timber architecture of its time. Liang Sicheng cites it in his book for that reason.
