Technological education in workshops. Tibetan artisans engaged in household production for generations. Along with the expanding of production scope, enhancement of product quality and division of work, private workshops appeared, such as the carpet workshops in Gyangze and painting studios in Lhasa. Driven by competiton, the workshop workers were organized to attend study sessions and particpate in examinations. This gave birth to a considerable number of skilled workers and technicians.
Hereditary education and individual apprentices. Hereditary education was one of the most popular ways of passing on scientific skills in Tibet. A father was normally a teacher of his son. And a son often inherited his father's property and carried on his work. This phenomenon was very popular, especially in bridge building, architecture, painting, sculpture, weaving and embroidery. Tibetan medicine practitioners normally had their own students as assistants. For example, Yutok Yunden Gonpo had 1,000 students. For this, he was seen as a model teacher. Astronomy and calendaring were taught also in this way with the result that some people were capable of foretelling weather, a boon for farming.
