Can't you go to the cemetery after beginning of winter?

Yes, going to the grave has nothing to do with the solar terms.

Beginning of winter, a solar term, was highly valued in ancient times. At that time, the emperor personally led his ministers to meet the winter weather, and there were folk customs such as ancestor worship, catering, divination, and offering sacrifices to ancestors with the best seasonal products.

In the past, on this day in early winter, people also held activities to worship ancestors and heaven. Even busy farmers have to rest at home for a day, kill chickens and sheep and prepare seasonal products. On the one hand, they sacrificed their ancestors to fulfill their obligations and responsibilities to future generations. On the other hand, they offered sacrifices to heaven, thanked God for giving them a bumper harvest, and prayed that God would give them good weather in the coming year.

Extended data:

? Beginning of winter is not only a time to hold a grand harvest festival and a harvest feast, but also a season of cold wind. There are customs and activities such as "October New Moon", "Qin Sui Shou", "Cold Clothes Festival" and "Harvest Festival". At this time, in the north, it is the winter months when the water freezes and the ground begins to freeze, but in the south, it is the weather of Xiaoyangchun.

In some areas of southern China, it is always warm as spring during the winter solstice and the Light Snow Festival (equivalent to October of the lunar calendar), so that some fruit trees mistakenly think that spring has come and bloom for the second time. As the saying goes, "it's warm in August and warm in September, and it's sunny in October."

In the dead of winter, the so-called "March 9 cold" is usually when it is not too cold before the winter solstice. Starting from the winter solstice, every "nine days" is counted as a "nine", the first nine days are called "one nine", the second nine days are called "two nine", and so on.
