视频中，一位戴着帽子和口罩的人正在安装一个木制的架子。他手持一块木板，用锤子敲击固定在墙上的木条，确保木板牢固地安装在架子上。背景是一面白色的墙壁，上面已经安装了两个水平的木条作为架子的一部分。整个过程显示了这个人仔细而专注地进行安装工作。
The video shows a person wearing a cap and a brown jacket, working on a wooden shelf. The individual is holding a piece of wood and appears to be sanding or smoothing it with a tool. After finishing this task, they move to the right side of the frame and begin working on the upper part of the shelf, possibly adjusting or securing something. The background is a plain wall, and the focus is on the person's actions and the shelf.
A man wearing a brown cap, glasses, and a mask holds a piece of wood in his left hand and a hammer in his right hand, standing in front of a wall with two horizontal wooden shelves. He positions the wood against the wall and begins hammering a nail into the wood. After securing the nail, he steps closer to the wall, holding the wood and hammer. He then places the wood down and uses his right hand to feel the wall, possibly checking the placement or securing the wood.
