What do she and Ji mean respectively in ancient sacrifices?

Simply put, the country is the land where crops grow.

In ancient times, society refers to the god of land, and is named according to its orientation: blue soil in the east, red soil in the south, white soil in the west, black soil in the north and loess in the middle. Five-color soil covered on the altar surface is called five-color soil, which actually symbolizes the country. In ancient times, the place, date and ceremony of offering sacrifices to land were also called clubs. Millet refers to the god of grains, especially the original god, that is, the land god who can grow grains. This is the god of agriculture. Sun Chengzong's reply to Yuan Jiehuan (Yuan Keli): "However, the people who save trouble in the world are not very obedient. They are delayed by the sun and the moon, which makes the parties extremely heavy and unwilling to return, so they are far-sighted for the country."

"Country" reflects the social nature of China's ancient country based on agriculture. The two were originally unrelated. The word "she" is the same as the word "earth" in Oracle Bone Inscriptions, both of which are written as "∏", like female genitals. In other words, she originated from the reproductive worship in primitive times. In the Spring and Autumn Period, you can also see the aftertaste of this primitive worship. Society, like "earth", was later added next to "water" and became the name of the land god. The altar of social sacrifice is also called "society". From emperors to princes, anyone who owns land can set up a community, and even villagers can set up a community to worship the land god. Social Day has become a day for good neighbors to get together, and there are various celebrations, such as "social drama" and "social fire". The word "society" in modern life is also related to social activities. Ji Yuan was the ancestor of Zhou people, Hou Ji, who was honored as the head of the five grains in the Western Zhou Dynasty, and sacrificed with the society, which was collectively called "the country". According to Zhou Li Kao Gong Ji, the social altar is located on the right side of the palace, opposite to the ancestral temple on the left side of the palace. The former represents land and the latter represents blood, both of which are symbols of the country. "Book of Rites under Quli": "The monarch died in the country." It means the monarch and the country live and die together.

The literal meaning of "country" is the land god valley. In order to pray for national peace, the ancient monarch went to the suburbs every year to worship the land and grain gods. The country also became a symbol of the country, and later people used "country" to represent the country. "Worried about the country", "afflicted country", "endangered country", "volunteered" and "sincerely follow" all refer to the country's worries, hidden dangers and security. This kind of article, which represents the general modern vernacular, is rarely used.
