As winter deepens in China, there is one special day that carries profound cultural meaning: Dongzhi (冬至), the Winter Solstice Festival. While it may not be as internationally famous as Chinese New Year, Dongzhi is one of the most important traditional festivals in Chinese culture—centered on family, balance, and the return of light. Often described as a day when winter reaches its peak and spring quietly begins, Dongzhi is a celebration of warmth in the coldest season.
