The winter solstice is the 22nd of the "24 solar terms", which is regarded as a major festival in winter. In the winter solstice, we'd better eat a variety of foods, the grain, fruit, meat and vegetables can be matched reasonably, and we can also selected the high calcium food appropriately. Northerners eat dumplings, southerners eat Tangyuan,  Shandong people drink mutton soup, Jiangsu, Zhejiang and Shanghai eat Fried glutinous pudding etc. At the same time, we also need to pay attention to maintaining full sleep and light diet.
