This kind of education was divided into two parts. One way was that feudal lords, noble families, officials and businessmen employed tutors to teach at home; the other referred to private schools located in major cities and towns. Tutors and private school teachers were those who were good at Tibetan. Students included children of noble families, rich people and businessmen as well as family servants specially charged to serve the former. Private school eventually became large in scale. In the early period of the 1840 Opium War, there were some 10 private schools in Lhasa, Xigaze, Gyangze and some other places. During the period of the Republic of China, such schools numbered nearly 100. Their students learned to recite Buddhist scriptures, to read and write and to count. In the later period, their curriculum included letter, document, and treaty writing.
