Jiangshi

Jiangshi are undead creatures bound to follow blood written commands written on special slips of paper and attached to them. Because the corpses raised to become Jiangshi must be at least one day old, the effects rigor mortis on their bodies prevents their knees and elbows from bending, forcing them to move around via hopping with their arms extended either forwards or out to their sides. 
When a Jiangshi has multiple slips attached to them, they try to follow all the orders they are given simultaneously. As this is not always possible, they prioritize certain slips based on three key factors. The first factor is when a slip was placed, with older slips receiving higher priority. The second factor is the strength of the blood with which the command was written, giving higher priority to the higher quality of blood. The final is the location of the slip on their bodies, with the highest priority given to those at the center of their forehead, the second-highest priority given to those centered on their chest, the third-highest priority given to those centered on their throat, and the fourth-highest priority given to those centered on their loans. Slips not directly centered on these locations are given the descending levels of priority based on their distance from the nearest of these key points, and as such, once all four of these slots are taken or otherwise sealed, the remaining areas of highest priority are located on the creature's head. Due to the size constraints of the slips, it is difficult to give a Jiangshi a detailed set of instructions; however, through the use of multiple slips, it is possible to "program" them into fully autonomous beings.
