三年困难时期
The Great Chinese Famine (, "three years of great famine") was a period between 1959 and 1961 in the history of the People's Republic of China (PRC) characterized by widespread famine. Some scholars have also included the years 1958 or 1962. The Great Chinese Famine is widely regarded as the deadliest famine and one of the greatest man-made disasters in human history, with an estimated death toll due to starvation that ranges in the tens of millions (15 to 55 million).
