Let's say a soldier is seriously wounded defending a city during a siege. What would they do with him? If he lived in the city he was defending, would they send him home or would they set him off to the side with other such injured.

I would think, they would send him to a place where the doctor can treat him..

I meant if the soldier was seriously wounded and was going to die. If they lived in the area, would they send him home to die? The reason I ask is because I recently read about the 6 month siege on Kaifeng in 1642 (prior to the flood).

Logically, they would just set him off to the side with other casualties (wounded, dead). This is just based upon my own experience in the U.S. Army. But I have no idea what the Chinese would have done in late Ming Dynasty China.

I would think that if the soldiers were locals, their family members would come seeking their news quite frequently (like every day). If they were seriously wounded and almost dying, I would think the family members would request to get them home. I seriously doubt that the officers and military doctors would be against that. It would help to reduce the mouths to feed by the army and the military resources that would spend on someone who was dying. I think in most time during the imperial China period, most Chinese army was run like any other European armies at the time -- not very organized and many civilians were in and out of the military camps. Only a few very good generals ran their army camps tightly and efficiently. Many armies in different dynasties had standing military orders that no women should be in the camp and no gamblings. However, I doubt those orders were strictly followed because there were records of soldiers and even officers kept on violating these orders and got into trouble when some good generals took over the camps and the army.
