Distances and Travel Times

[Mysterysword]

I was mainly trying to work it out based on how "Yanxia" should be pronounced: the Southern Chinese way ("Yan-sia"), or the Northern Chinese way ("Yan-sha", or stereotypically "Yan-sharrrrr").

I thought "Yanxia" was another varient, possibly a Mandarin dialect pronunciation, of "天下", pronounced "tiānxià", the concept of "All under Heaven".
