The winter solstice is a very important festival in ancient times. There is a saying that "the winter solstice is as big as a year". Our ancestors always count nine from this day, and record the phenological changes of the spring equinox from the winter solstice to the next year. On this festive occasion, let's bless each other and celebrate together. In the longest winter night, wait for the photos of spring. Suzhou Xinkunyuan Environmental Technology Co., Ltd.
