Guo Moruo's Historical Draft of China pointed out that the Zhou Dynasty was a vassal with the same surname in Sui and Zeng States. 1979 Two bronze inscriptions of Ge Ming were unearthed in a tomb in Gangji Liang Shi, a suburb of Suizhou. The owner of Tongquetai is Ji Yi, the son of Great Mother and the descendant of Xigong. According to the inscription, Lao Lao claimed to be "the grandson of Zhou Wang", which proved that Zeng Hou was originally a descendant of Zhou Wang. On this basis, Tan Sitong concluded that Zeng was the surname of Ji, and his monarch had the same surname as Zhou.
