Walkthroughs for custom maps.

And here are the words of the map author:

I am awfully sorry that the map does not have an English version. There are millions of words, including some poems and couplets, and some Chinese word puzzles, which are hard to translate.

Xiedu, in turn, wrote that his map is still too complex for most players, so there's no point in bothering with a translation.

I think that if translations of the most famous Chinese maps haven't appeared yet, it's unlikely that they will be made in the future.
