How did the word tortoise come from?

There have been various opinions about the origin of the name "tortoise" in the past. For example, according to the records in the History of the New Five Dynasties and the Family of the Former Shu, the "tortoise" refers to Wang Jian, the former Shu master during the Five Dynasties and Ten Kingdoms. Because Wang Jian was a rogue when he was young, he specialized in stealing donkeys, slaughtering cattle and selling illicit salt. Wang Jian ranked eighth among his brothers and sisters, so people in his hometown called him "thief bastard". Another way of saying this is that the homonym of "tortoise" or "forgetting eight" refers to people who have forgotten the eight virtues of "courtesy, righteousness, shame, filial piety and faithfulness". (See Zhao Yi's "Yu Cong Kao") Although the above two statements are not unreasonable, the "tortoise" mentioned is not taboo among the people.

The "tortoise" taboo among the people refers to the tortoise. Because "tortoise" is another name for tortoise. (The tortoise is commonly known as "tortoise" among the people) Why is the tortoise also called tortoise? Just read Historical Records Biography of Tortoise. In this Biography of Tortoise, supplemented by Chu Shaosun, a historian of the Western Han Dynasty, the author divides the "tortoise" into eight kinds according to the legend that the three kings and five emperors in ancient times used "tortoise" and yarrow to prophesy. Each species has a name, and the eighth species is called "Wang Gui", so later generations will call this eighth "Wang Gui" tortoise for short. Over time, "tortoise" has become another name for tortoise, and people often use tortoise and tortoise together. For example, in Yong Xi Yue Fu compiled by Guo Xun in the Ming Dynasty, there is a poem "The Order of Wandering and the Order of Folding laurels", which connects "turtle" and "tortoise" to refer to the same kind of person: "Shrimp's waist, turtle's generation, jade chain can't be tied with incense ribbon; A tall-ridged, thin-twisted, green-furred tortoise cover. " It can be seen that the so-called "tortoise" refers to the tortoise, which is an alias for the tortoise. Since the tortoise is also commonly known as the tortoise, people are bound to avoid calling the tortoise at the same time.
