It is the name of a good horse in ancient China, produced in the northern wilderness of the north. Before the Qin Dynasty, the vicinity of the State of Lu (Shandong Province) was called Taiye, and the ancient Yanzhou was called Daye. Kitano, or Yanzhou in Shandong Province, further north, roughly includes modern Hebei Province and its northward end, so it is highly likely that it is the ancestor of the Northeast horse or the Mongolian horse. Both horses have cyan breeds.
窭僮 (jù具同, no) indicates that the student has not completed his studies and is still in the Montessori stage. The original meaning of 夭騊 refers to a thousand miles of horses between the ages of half a year and one year old, which is used here as a metaphor for students who have just gone from "not clear" to "rough". 窭僮 (jù具同, tong) refers to the primary student (preschool), and 騊騊 refers to the student who is just getting started (first grade of primary school).
