"Night Sailing" is not only an encyclopedia, but also the world in the eyes of the author Zhang Dai. Night sailing is a symbol of the long and arduous journey in the ancient southern water towns. People have to take a boat when going out. During the slow sailing, if they are bored, they will entertain themselves by chatting about everything. "Night Sailing" is not an enigmatic ancient book, but a piece of cultural common sense narrated in relatively simple classical Chinese. Most of these entries are content that people should be familiar with, including twenty chapters such as astronomy, geography, characters, archeology, and ethics. "A Complete Guide to Night Sailing Ships" carefully annotates and translates its contents, making it easier for readers to read during their busy schedules.
