Director's Notes：In Search of the Genglubu

In 2014, we visited the home of fishing boat captain Su Chengfen in Tanmen, Hainan Province. He showed us a weathered handwritten manual – the Genglubu. We had no idea that this would become a story we would continue to follow for more than a decade. Over the years, we returned to Tanmen time and again, searching in museums, archives and universities for surviving copies of the Genglubu.
