What are the classic family precepts in ancient China?

Clan characteristics 1. There are many generations of Gao surnames in various places. Some families have lasted for hundreds of years, and a word line was used in the fifties and sixties. For example, Sichuan Gao's ci behavior: "Knowing the grace pavilion, the person who should be wise and kind, Chang Rongwen, and bear the merits of governing the country." Some families, with the reproduction of their descendants, split into their own comprehensive branches, and each branch has its own line. For example, Wenzhou Pangu Yizhi (a descendant of Gao Qiong) has the following words: "Ji Mei Qi Yu, who knows the source carefully, is honest and clean, and cares first, and is unwilling to learn the scenery and celebrate the clouds." Some families inherit the bus of the whole family, and at the same time each branch of the word derives its own line. For example, the word line under the word "Zhi" of Tan Gaojia is: "Shang Jin can be closed, Xunlong Guibao meets Qian Chun, Teng Ji Xiang can seek his ancestors, and Xun You meets Bing Lin." 2. Every gaos thought's family rules and instructions are similar, and they are generally based on loyalty, filial piety and righteousness.
