Transitioning from a natural farming economy to a commodity economy meant that there was a need for profitable commodities. With this change money became important. This evolution in the society brought about a change in the folk art. The "Tree of life" turned into a "Tree that shed coins" or a "Treasure bowl." The goal in life was no longer to gain basic survival. Life and propagation gradually faded and was replaced by symbols denoting a happy life and good fortune. For example, by combining two items such as a halberd (symbolizing favorable circumstances) and jade (symbolizing fulfillment of ones wishes) auspicious good fortune would replace the original concept of perpetual life. Having many children was symbolized with lotus in a vase. Another example to have every wish granted was expressed by combining two persimmons with jade. The persimmons were symbolic of having everything. The life view changed from simple propagation to living comfortably with extras. Looking at Chinese folk art through different times is like separating cultural layers at an archaeological site. Every shard carries the trace of the historical culture of its time.
