Final answer:
Early Chinese artists indicated depth in their paintings by overlapping bodies of mourners, scaling foreground objects larger, and background objects smaller, utilizing these techniques to achieve a three-dimensional effect.
Step-by-step explanation:
In early Chinese painting, artists used various techniques to indicate depth in the mourning scene. These techniques included: overlapping bodies of the mourners to create a sense of one figure being in front of another, scaling objects in the foreground larger, and making objects in the background smaller to imply distance. All these methods contributed to a three-dimensional effect on a two-dimensional surface, suggesting spatial relations and depth in the composition of the scene. These methods were integral to traditional Chinese artistic representations to create a narrative and emotional depth.
