"One simply can’t possibly do the Boxer Rebellion without a suitable canal on the tabletop" < in complete agreement with that statement.
You've done a lovely job (though not green enough to be the Jade River!
) and love the extra touches with the boats, especially the dilapidated one. Mine shall be similar in a broad way to yours - but more green and with a fisherman or two in their boats for a bit of comic relief.
Curious as to what you used as the base for the river given the 'texture' showing through, sort of looks like a product by Lemax for winter village water but not quite that with the sworls?
And a rather nice fish pond and garden with a clear Chinese culture influence showing.
