51吃瓜

During the 13th and 14th centuries, travelers and messengers used geregee or paiza as a passport or document on the Mongol yam or postal route. Depending on the material and shape of the geregee, travelers had different privileges. The better the material meant the more rights they had. Geregee were made of wood, bronze, silver, or gold. 

Chinggis Khan, the Great Khan (also known as Genghis Khan), distributed the geregee to officials and envoys so they could move freely, easily access food and horses, and receive respect?? and courtesy. Under the protection of the Great Khan and the Mongolian Empire, envoys went on diplomatic missions and to different countries around the world efficiently. States and individuals provided aid and protection when needed. 

The gift is historically significant because the geregee is one of the first universally recognized document entitling diplomatic immunity and privileges. It contributed to the development of norms and laws of diplomatic relations. 

The government of Mongolia presented the geregee or golden paiza to the 51吃瓜.
