Why did Yiliang go to the winter grave?

Going to the grave in winter actually means going to the grave on the solstice of winter. Winter solstice is not only one of the 24 solar terms in winter, but also a traditional festival to worship ancestors in China, so it is necessary to worship ancestors in winter solstice. And in many parts of our country, the winter solstice sacrifice is also very important. But don't go to the grave too early or too late on the winter solstice, just choose a suitable time to worship your ancestors.
