Although both civilizations, Roma in the west and China in the east, had an inkling of each other, the direct contact did not occur due to hardship natural environment between them. However, intermittence contact had been made via small countries located in the middle.
In 2 B.C., Janggeon who was ordered from Wu Di (Muje), emperor of Han (One of ancient China's countries) explored up to the outside of India for the first time. Due to that, safer route which could be connected with each other had been opened. Via that road, the Chinese silk began to flow to Roma in Europe.
