The Autumn Equinox is the sixteenth of the twenty-four solar terms and the fourth in autumn. On the Autumnal Equinox, the sunlight is almost directly shined on the Earth's equator, and day and night are equal in length around the world. On the Autumnal Equinox, "fen" means "equal division" and "half". In addition to the equal division of day and night, there is also a layer of meaning equal to the division of autumn. After the Autumn Equinox, the position of direct sunlight moves southward, the days in the northern hemisphere are shorter and the nights are longer, the temperature difference between day and night increases, and the temperature drops day by day. During the Autumn Equinox, the traditional Chinese festival is the Mid-Autumn Festival. On this day, people gather to admire the moon, chat and hang lanterns to celebrate the festival.

This project refers to ancient Chinese paintings, trying to restore how the ancient Chinese spent the Mid-Autumn Festival.

秋分，是二十四节气之第十六个节气，秋季第四个节气。秋分这天太阳几乎直射地球赤道，全球各地昼夜等长。秋分，“分”即为“平分”、“半”的意思，除了指昼夜平分外，还有一层意思是平分了秋季。秋分日后，太阳光直射位置南移，北半球昼短夜长，昼夜温差加大，气温逐日下降 。在秋分时期，中国传统节日是中秋节。中秋节这天，人们聚在一起赏月，聊天，挂花灯。

这个项目参考了中国古代画作，竭力还原中国古人如何度过中秋节。
