According to my information, Dreamworld Kingdom () does have a nighttime venue called 夜场 (Ya Chan) with various entertainment options, including music performances and laser light shows.
Regarding fireworks displays (), it seems that they do occasionally hold fireworks shows as part of their special events or celebrations. However, the frequency and details may vary depending on the time of year, holidays, and other factors. I recommend checking their official website or contacting them directly for more specific information.
