The Silk Road, associated with the name of the Chinese ambassador Zhang Jian, gained widespread development in the I-II centuries. Trade with China was mainly carried out by Central Asian intermediary merchants. In 97, the Chinese traveler Tan In reached the Persian Gulf. In May 100, Titian reached Longzhou, but the difficulties in the journey prevented him from connecting China with Rome.
