Qilu culture, accurately speaking, is not a single culture, but a fusion of Qilu culture. During the Spring and Autumn Period, Confucianism, represented by Confucius, was formed in Shandong, and Qi, which borders the eastern coast, absorbed and developed the local culture (Dongyi culture).

These two ancient cultures are different. Comparatively speaking, Qi culture attaches importance to utility, while Lu culture attaches importance to ethics. Qi culture pays attention to innovation, while Lu culture respects tradition. In the process of development, the two cultures gradually merged organically, forming Qilu culture with rich historical connotation. "One mountain, one water and one saint" is the essence of Qilu culture. Mountain refers to Mount Tai, sage refers to Confucius, and water refers to the Yellow River (also known as Baotu Spring). The phrase "one mountain, one water and one saint" comes from Liu Gonggu, the champion of Dongping in Qianlong period of Qing Dynasty. Liu Gongfu was very poor when he was a child. He studied hard, and later Confucius became a university questioner.

Later, Liu Gongfu became an official in the south, where many of his famous couplets caused a sensation. It is said that when he first arrived in the south, many local scholars wanted to make it difficult for him to pass the exam. They gave him couplets. Some local geniuses and his couplets. One of them said, "There are many mountains and waters in the south of the Yangtze River, so there are many talents." . Liu Gongfu said: "One mountain, one water and one saint in Shandong". The core of Qilu culture is Confucianism. It can be summarized as the spirit of self-improvement, patriotism, pragmatism, determination to win glory, people-oriented spirit, humanistic spirit, selfless spirit and hardworking and intelligent spirit.

Qilu ancient culture is prosperous and splendid, and sages come forth in large numbers, which is superior to other regions. In addition to the superior natural conditions, the motive force of national integration and the above-mentioned basic spirit, there is another point worthy of in-depth study, that is, the creative spirit of Qilu culture, which is often overlooked.

Qilu culture is extensive and profound, so it is difficult to generalize. I think loyalty, kindness, hospitality, courage and tolerance are the concrete manifestations of Qilu culture. To understand Qilu culture, it is suggested to start with tourism, travel around Shandong and experience Qilu culture.
