People's livelihood refers to the basic means by which individuals secure their necessities for living, such as food, shelter, and economic stability. This concept was a central focus during the early Republican period in China, especially under the influence of Sun Yat-sen, who emphasized the need for social and economic reforms to improve the lives of the Chinese people. The notion of people's livelihood was integral to creating a modern nation and addressing the widespread poverty and inequality that characterized China at the time.
