视频中，一位戴眼镜的男子坐在沙发上，手里拿着一个麦克风和一个计算器。他似乎在进行某种演示或讲解，表情专注且认真。背景墙上贴满了各种文字和图案，营造出一种独特的氛围。桌子上放着一些文件和笔记本，显示出这是一个工作或学习的环境。灯光柔和，给人一种温馨的感觉。
In the video, a person is sitting on a patterned couch in a room with a menu board on the wall behind them. They are holding a microphone in one hand and a large calculator in the other. The person appears to be speaking or presenting something, possibly related to the calculator they are holding. The setting suggests a casual or informal environment, perhaps a restaurant or a similar venue.
A man is sitting on a patterned blue couch in a room with a wall covered in song lyrics, holding a microphone in his left hand and a white device in his right hand. He rotates the device to show its front side, which has a keyboard and various buttons. The man continues to hold the device up, displaying it to the camera while speaking. He then turns his head to look at the device and back at the camera.
