How to set off fireworks in QQ games?

Hello, after entering the game hall, you can see the "horn" and "fireworks" buttons in the lower right corner. After clicking, enter what you want to say in the pop-up box and click "Send". Send a small speaker, so that everyone in the room can clearly hear your voice (except QQ show chat room, QQ hall, QQ game house). In addition, the limited-time speakers obtained by the activity and the special speakers purchased by the game mall are valid in the current month and uniformly emptied at the end of the month. Please pay attention to timely use. Send fireworks and your words will be displayed in the center of the room with colorful fireworks! All the players in the hall can see it. Oh, it's beautiful. On your birthday or when something happy happens, you can set off two fireworks to celebrate. Hall support of 2007beta2 or above is required. Fireworks are valid in that month, please use them in time! At the same time, after speakers and fireworks are used up, they can also be purchased through the props bar of the game mall. I hope you have a good time!
