Here's a description of the video: The scene features a group of people playing traditional instruments. Two cymbal players are positioned on either side of a large drum, which is being played by two people wearing matching uniforms in green and white. Behind them is a large screen displaying a lion dance performance in front of a crowd. To the right is a scaffold structure, and in the foreground, there is a table with a sign that says "KIEM TRA BAI THI" along with bottles of water. The event seems to be taking place outdoors, during daylight. A banner with the words "ĐẠI SƠN" is displayed behind the drum.
