China uses so many stages on their rockets. Are they not able to build larger durable systems so they just stack them up? It just adds more failure points, like here with the 4th stage failing. Most other launch systems we're talking 2 stages until the payload, maybe 3 for some deep space launches.

It's probably because this is all solid stages. Since you don't have throttle control or the ability to stop and start the engines with solid motors if your building an entire launch system built around them you use more stages.
I seem to remember some early US rockets with an unusually high number of stages by today’s standards, so maybe that’s the level of technology this company’s at.
It could point to a limitation of the rocket motor design. Kerbal is a good way to learn that there are 2 ways of solving the problem of too much weight and not enough thrust: more rockets or more stages.
