According to South Korean media reports, the Buyeo Institute of Cultural Property of South Korea said on the 27th that when excavating the tombs of King Wuning and Wang Cemetery in Gongju, Chungcheongnam-do, the bricks made by ancient Chinese craftsmen were found. During the investigation of the masonry at the entrance of Tomb No. 29, the words "This is the builder of this" were found on the side of the lotus-patterned sealed brick cut in half. It is reported that Jianye is the ancient name of Nanjing, China, which means that brick craftsmen come from China. However, at that time, the Jianye people only participated in the construction of masonry or the entire stone tomb, and it was difficult to draw conclusions.
