Did Huainanzi mention the winter solstice?

Astronomer Xi said: "The names of the twenty-four solar terms first appeared in Huainanzi Astronomical Training. In fact, all the handed down documents in the pre-Qin and early Western Han dynasties did not record the twenty-four solar terms completely and scientifically. This major scientific research project was completed in the second year of Emperor Jian Yuan (BC 139), and Liu An, the king of Huainan, dedicated Huainanzi to the emperor. The starting point of the twenty-four solar terms is the "winter solstice". The Astronomical Training of Huainanzi and the Training of Huainanzi's Teachers not only record the laws of the sun's movement, but also record the contents of astronomy, calendar, temperament, four seasons and so on.
