Guoshou (国手, lit. national hand) was a title of strength recognition bestowed upon the top players in ancient and classical Chinese go. The term is usually seen as a less restrictive form of the Japanese meijin title, in that many players across the country could have the title simultaneously. This was a result of the lack of national institutions present (unlike classical Japanese go) to establish a single guoshou among the many local/regional ones. Nonetheless, occasionally near-national consensus could be reached to declare the top guoshou, or daguoshou (大国手), such as in the case of Guo Bailing. Stories of guoshous challenging each other and the outcomes are the main ways that historians have to try to determine who the 'top' guoshou(s) might have been during a given period.
The following players were given the guoshou title (incomplete and unordered list):

valerio: I think Fang Weijin is not the correct name; I think the right name is Liang Weijin.
