Moreover, these two Japanese have lived quite well in the Great Zhou over the years, and they do not wish to return to a life of turmoil. Additionally, they have no affection for their homeland. They only harbor hatred for Japan and would not be willing to lose the good life in the Great Zhou for Japan.
However, these two Japanese did not receive any education while in Japan, and they are not intelligent. The maps and sea charts they drew cannot be fully trusted. Zhao Yao mentioned in the letter to He Lianfang that these maps and sea charts can only be trusted fifty percent.
He Lianfang first opened the sea chart and examined it carefully. He had never been to the sea and did not know where the issues might be. He decided to send people to the coastline of Eastern Wu to inquire from the fishermen, some of whom had been to sea and entered the waters of Japan. Although they did not ultimately reach Japan, they were somewhat familiar with the route to Japan.
