Is the winter solstice highway free?

There is no holiday from winter to Sunday, and the expressway is not free.

In the winter solstice, the sun moves to 270 degrees of the yellow meridian (winter solstice), and the position where the sun directly hits the ground reaches the southernmost point of the year. The sun is located almost directly on the tropic of Capricorn (also known as the winter solstice daily line), and the sun is most inclined to the northern hemisphere. Therefore, in all parts of the northern hemisphere, the winter solstice is the shortest day in a year, and the farther north, the shorter the day. North of the Arctic Circle, the sun is below the horizon all day, which is the widest day of the year in the northern hemisphere.

For all parts of the northern hemisphere, the winter solstice is also the day with the lowest sun height at noon all year round. As far as Beijing is concerned, the daytime from winter to sunrise is only 9 hours and 20 minutes, and the height of the sun at noon is only 26 42'. During the winter solstice, the northern hemisphere gets the least solar radiation, about 50% less than the southern hemisphere. The winter solstice is a sunny day, and the new year begins.

"Collection of Classics" states that "summer is the end of the autumnal equinox, spring is the winter solstice", and the winter solstice festival is the first sound of spring. After the winter solstice, the stars in the night sky are completely replaced by the stars in winter. From today, they will enter the ninth. At this time, the southern hemisphere is in a hot summer.

Winter solstice is the earliest of the 24 solar terms, but most people don't know that the origin of winter solstice actually comes from the planning of a national capital. As early as more than 3,000 years ago, Duke Zhou began to measure the shadow with the earth gauge method and measure the position of the world in Luoyi. This was a move of political significance at that time, but it became one of the festivals that affected future generations for thousands of years.

When the Duke of Zhou arrived in Luoyang, he measured that Luoyang was "in the world" by the method of returning to the soil, and then began to divine the country and the land. It is recorded in Shangshu Luogu that the Duke of Zhou "Panluo City" made some investigations in several places around Luoyang, and finally determined that Jianshui East, Zhuoshui West and Zhuoshui East are "Weiluo City" (all good places to build ancestral halls). The historical fact that the Duke of Zhou chose the base site of Luoyi through the "investigation of returning to the land" was recorded in ancient books and was regarded as the law of sealing the country by later generations.
