==Chinese Dynasties and Empires==
During the Shang Dyansty (1600-1000 BCE), researchers have stated the climate became generally warmer. Warmer conditions lasted until about 350 CE, covering nearly eight dynasties and ending around the Six Dynasties period. During warmer periods, citrus, such as oranges, may have made their way to China and began to be incorporated into diets. After 350 CE, much colder conditions became evident in northern China, with much harsher winters. This may have led to the development of ice houses for the first time, which allowed better preservation of food over the winter periods.
However, over the last two thousand years, as climate has become drier and colder in parts of eastern China, there has been greater evidence that this has led to more periodic locust, famine, and drought occurrences. This has also led to higher incidents of epidemics, where drought and famine created better conditions for epidemics as the population became weaker to resist such incidents.
