It would be great if the source or sources according to which the author made this map were listed. As it stands, it seems to me that there is no way to verify whether or not this is, in fact, an accurate description of the Beijing city wall.
Furthermore, although I'm personally aware that this map shows Beijing as it was during the most of the Ming and Qing dynasties, there is no mention of this anywhere. "Map of Beijing city wall" is too vague a description. -- Anthee (talk) 19:57, 23 June 2008 (UTC)
