The discovery of olive trees can be traced back to12nd century BC. It is generally believed that Asia Minor was the earliest place where people planted olive trees, about six centuries ago.

In fact, the origin of the olive tree is still unknown, but with the birth and development of Mediterranean civilization, the olive tree has been closely related to the fate of mankind for thousands of years, leaving a rich and colorful stroke in western culture.
