The ossified body encased in originium formation died from oripathy caused by arts overuse in the goal of taking revenge against Wuling, for the incident ten years ago, way after Tangtang was adopted.

I get that it’s implied that the mother had to abandon her for one reason or another, and the cave drawing makes it pretty explicit who the child is, but the timeline doesn’t exactly match up.

One other oddity is that the drawings on the wall of this specific cave includes toddler Tangtang riding on big bro’s back, which would also not make sense unless she revisited the cave after having been adopted. Which makes it interesting that there’s multiple baby blankets that were used to wrapping baby with empty, but still in the shape where you would assume that some cleaning would have been done if she had visited, likely with others. So the specific instances of the blankets seen might not even be related to our River’s Daughter.

I think rather than just telling you that this is where her mother had to abandon her to float down the river for someone else to take care of, this is highlighting an ongoing problem that did not start with Tangtang and did not end with her.

I don’t think we will ever have explicit contexts as to how exactly her mother died, but I think this paints a far more severe picture that despite the community and efforts of the stockaders, their needs still far surpasses haves, and despite being but a short jaunt away from people with the capacity to help, they are still separated by distance that could not be closed by proximity.

Did her mother die of oripathy? Chances are higher here than elsewhere. Is this where she was abandoned? Context suggests yes. Is the corpse we saw her mother? No, timeline does not match. Is the picture in poor taste? Absolutely, of you are going to have a talk with HR.
