中国国家博物馆
In a 2001 article entitled “Introductory Explanation of the Shi Shan Pan Inscriptions”, Song Fenghan (朱凤瀚) writes that the inscriptions on Shi Shan Pan artifacts in the National Museum of China mention Ruo and thus show that such a state existed at the time of the Western Zhou Dynasty. Zhou Baohong (周宝宏) also makes the association between the State of Ruo and the Spring and Autumn Period.
