the circle is a morphological symbol of Chinese traditional culture, symbolizing "perfection" and "fullness", and it is a totem advocated by China people who value harmony since ancient times. The combination of full harmony and round is called the perfection of Chinese characters, which is saturated with the simplest philosophy of the ancestors of the Chinese nation. If the circle is full, it will be round. If you have a perfect heart, you will have peace and contentment. If you value harmony, you will be able to take the golden mean, and you will not be unbalanced and anxious because of extremes.

The full moon is used to describe the fifteenth full moon. In the culture of China, the moon's waxing or waning is often used as a metaphor for human affairs? Therefore, people have a beautiful expectation and worship for the full moon, especially the mid-autumn on August 15th every year, which is called Mid-Autumn Festival by the people, also known as Autumn Festival, August Festival, August Half-Day, Moon Festival and Moon Festival, and because the full moon symbolizes reunion on this day, it is also called Reunion Festival. On the night of the festival, people also like to eat some reunion fruits such as watermelons, and wish their families a happy, sweet and safe life. Therefore, the full circle is regarded as a great symbol of family reunion.

the relationship between roundness and fullness: Chinese ancestors thought that "the sky is a round place", so they took "roundness" as the representative of the sky, and at the same time regarded the 15th full moon of each month as a symbol of fullness and associated it with the harvest of fruits. For thousands of years, the philosophical spirit generated by farming cultures such as "Spend a full moon well", "Fiona Fang's way" and "complete merit" has been nourishing China people endlessly, and "roundness" has an irreplaceable position in people's minds.
