Apropos of nothing really, but sort of interesting...
From a quick google, it seems there are a staggering number of mislabelled photos/plants out there, that are claimed to be Lysimachia lichiangensis, but appear instead to be various yellow-flowered Lysimachia spp. (often L. punctata). :o (This, even from some nurseries! ???)
Here is the eFlora of China description, which describes the flowers as white to pink, for starters:
Photos that might be correct are few and far between, and seem to show only the flower spike or basal seedling leaves - not the entire plant. Does anyone grow it? I'd love to see photos of the mature plant.
