This work is produced with AI assistance. Ji Du has been ferrying at the pier for twenty years, insisting on operating the boat only under safe conditions and never taking risks due to urging. Facing A Du's request to learn ferrying, she uses repeated waiting and judgment to tell her apprentice that true ferrying is not just crossing the river surface, but safeguarding everyone's safe arrival. Between the pier and the river water, the master and apprentice pass down experience, allowing the younger generation to understand the meaning of responsibility and patience.
