Introduction to the starting point of Xu Fu's eastward crossing: On the port pier of Langya Port, there is a stone tablet inscribed with "The starting point of Xu Fu's eastward crossing". According to "Historical Records", Xu Fu's eastward voyage to Japan set sail from Langya Port in front of Langyatai. In ancient China, Langya Port has endured for a long time and has always been an important shipping port and coastal defense location. Now, the port not only has fishing boat terminals and cargo terminals, but also has a tourist terminal. Qingdao-Langyatai Marine Tourist Ferry Terminal is here. Not far from the east and west side of the stone monument where Xu Fu set sail for his eastward journey, there are the ancient shipbuilding sites of Chaowan and Zhewanzi. Local residents said that these were the sites where Xu Fu built building ships for his quest for elixirs and for his eastward voyage to Japan. .
