Happy winter solstice Monday, 21 December Dongzhi Festival 2020. Winter Solstice (Dongzhi, 冬至) is the 22nd solar term in the Chinese lunar calendar which marks the arrival of the bitterly cold winter season. On this day, the Chinese will eat dumplings or tangyuan, carrying an auspicious reference to the reunion of family
This marks the start of winter.
In olden agrarian society of China, this festival is an even more important festival than CNY, especially in families with aged parents or grandparents.
Winter is the most trying and health sapping of time. Many weak old people will not survive through. So there is a gathering of whole families on that night as it may be the final time for a few old timers.
As winter has onset, all harvesting has been done. Using the newly cropped rice, tang yuen is made and the round shape signifies the complete circle of family members on that day as it was partaken.
That's why there is also a saying that you are one year older after eating tang yuen. This is to promote the elders one more years in age to bring good karma to survive through the winter.
This festival is not religious, but cultural. Please remember each of your origin. Every civilised race with a history has many such significances. Your location or citizenship can never erase your DNA.
