Problem: Please answer a question about the following article about Identity (social science):
As a non-directive and flexible analytical tool, the concept of boundaries helps both to map and to define the changeability and mutability that are characteristic of people's experiences of the self in society. While identity is a volatile, flexible and abstract 'thing', its manifestations and the ways in which it is exercised are often open to view. Identity is made evident through the use of markers such as language, dress, behaviour and choice of space, whose effect depends on their recognition by other social beings. Markers help to create the boundaries that define similarities or differences between the marker wearer and the marker perceivers, their effectiveness depends on a shared understanding of their meaning. In a social context, misunderstandings can arise due to a misinterpretation of the significance of specific markers. Equally, an individual can use markers of identity to exert influence on other people without necessarily fulfilling all the criteria that an external observer might typically associate with such an abstract identity.
What is a volatile, flexible, and abstract thing?
A: identity
Problem: Please answer a question about the following article about Sino-Tibetan relations during the Ming dynasty:
Patricia Ebrey writes that Tibet, like Joseon Korea and other neighboring states to the Ming, settled for its tributary status while there were no troops or governors of Ming China stationed in its territory. Laird writes that "after the Mongol troops left Tibet, no Ming troops replaced them." Wang and Nyima state that, despite the fact that the Ming refrained from sending troops to subdue Tibet and refrained from garrisoning Ming troops there, these measures were unnecessary so long as the Ming court upheld close ties with Tibetan vassals and their forces. However, there were instances in the 14th century when the Hongwu Emperor did use military force to quell unrest in Tibet. John D. Langlois writes that there was unrest in Tibet and western Sichuan, which the Marquis Mu Ying () was commissioned to quell in November 1378 after he established a Taozhou garrison in Gansu. Langlois notes that by October 1379, Mu Ying had allegedly captured 30,000 Tibetan prisoners and 200,000 domesticated animals. Yet invasion went both ways; the Ming general Qu Neng, under the command of Lan Yu, was ordered to repel a Tibetan assault into Sichuan in 1390.
When did the Hongwu Emperor use military force in Tibet?
A:
the 14th century
