：大虫皮制度是吐蕃王朝一项重要政治制度，根据军功以不同规格授于大尚论、边将、英勇士兵（虎兵），适用对象广泛。随着吐蕃对外不断扩张与交流频繁，仅依赖本土所产虎皮已无法满足于大量军功人员的衣饰需求，大虫皮告身虽以虎皮为主但也不限于虎皮，虎皮来源随之多元化，成为吐蕃与周边经济文化交流的内容之一。

The System of Tiger's Skin was an important political system of Tubo Dynasty. The skin was awarded to high-level Zhang Lon, frontier generals and brave soldiers (Tiger Soldiers) in different grade according to the battle military merit. With the continuous expansion and frequent exchange with the surrounding areas, the tiger's skins produced in Tubo could no longer meet the clothing needs of a large number of personnel with military merit. Although tiger's skin was the main form of certificate, it was not limited to tiger's skin, and the sources of tiger's skin were thus diversified. Tiger's skins had become one of the contents of economic and cultural exchange between Tubo and Its neighboring areas.
