There were a few things to consider when writing the dialogue of the characters in the script: 1. A conversation needs to have a level and rhythm. A conversation shouldn't be a simple statement, but a series of layered and rhythmic conversations. There should be a subject, a verb, and an object in a conversation, and there should be appropriate tone and intonation changes. 2. Conversation requires conflict and motivation. Conversation needs conflict and motivation to attract the reader's attention and move the story forward. The dialogue should include the purpose, wishes, and beliefs of the characters. These could add depth and meaning to the dialogue. 3. The dialogue should reflect the character's personality and psychology. The character's personality and psychology could be reflected through the tone, expression, and actions of the dialogue. Through dialogue, readers could better understand the character's personality and psychology, and thus better understand the story. 4. Use appropriate literary skills in dialogue. In the dialogue, appropriate literary techniques such as metaphor, parallel, and antithesis can be used to enhance the expressiveness and artistic appeal of the dialogue. In short, writing the dialogue of the characters in the script needed to pay attention to the rhythm, level, conflict and motivation of the dialogue. At the same time, it also needed to use appropriate literary techniques to enhance the artistic expression of the dialogue.
