1. First, determine the location of the concrete brown pole to be demolished, and find the connection point or insertion point in the model.

2. Then, you can use a small tool, such as a flat screwdriver, slender pliers or a removal tool, to help remove the brown rod more easily.

3. Then gently insert the tool into the gap between the brown rod and the adjacent parts, and then apply force appropriately, not too hard, so as not to damage the brown rod or other parts of the model.

4. Finally, you can feel the looseness of the brown strip, and gently twist or pull the brown strip until the brown strip is completely separated from the connection point.
