In the game "Meet Cold Water", the way to get letters through travel is to complete the travel task. Players can pick up the task in the tour interface, and then go to the designated place for exploration and travel according to the task requirements. In the process of completing the task, players have the opportunity to get letters from different characters, which can be used to unlock the personal plots and stories of the characters.
