To help me understand what you're looking for, please provide more context:
* Where did you encounter this word? (e.g., a book, a conversation, online)
* What was the situation? (e.g., someone was speaking, a text was being displayed)
* Do you have any other information? (e.g., the word's pronunciation, surrounding characters)
Once I have more context, I can better understand what "dzai" might refer to and help you find its meaning.
