Jingtianweidi introduction: Entering the Lingxing Gate is the first step into the courtyard. In the east and west walls of the courtyard, there is an outward-facing stone square built in the third year of Jiajing in the Ming Dynasty. Among them, the stone square on the east side is engraved with the four characters "Jingtianweidi", praising Zhou Gong for taking heaven and earth as the law, managing the world and bringing order to chaos.
