WI the Yellow River stays in the south

What if the Yellow River would have never changed it course to the north of the Shandong peninsula in the late 19th century? What would be the effects on Northern and Central China?

Not going to happen. Oh, you could get it to move earlier or a bit later, but the mouth of the Huang He has moved all over the place over the last few millenia. North, south, different locations both places.

Given that it shifts when the silt builds up a certain amount, you might have to massively change agriculture upstream to lessen the silt load. That kind of agricultural change (probably a massive disaster) would have as much/more impact as the change in the mouth. IMO
 
I don't want that it doesn't move I want that it stays in the south and doesn't turn northwards in the 1880s. Is that totally impossible with a POD in the 19th century?

Unless you get the Qing to decide on one of the largest Megaprojects in milenia to de-siltify the river and build vast walls, levies and stuff to force it to stay on the path it's on, it's pretty much not possible to prevent it from moving North.

Those projects were routine. The trick is that they could only handle it in peacetime. Once the Taiping reached the Yangtze, that ship had sailed. Perhaps even after the Opium War, really.
