1. Replace Jiuli board: the flexible film lamp is large in size. Consider replacing the Jiuli board, and reinforce and fix the periphery and bottom of the flexible film lamp with Jiuli board to ensure the stability and safety of the flexible film lamp.

2. Increase the support frame: The size of the flexible film lamp is small, so we can consider increasing the support frame around and at the bottom of the flexible film lamp to increase the bearing capacity and stability of the flexible film lamp.

3. Use other materials: Jiuli board can't be used, and other materials can be considered for reinforcement and fixation, such as wood boards, steel plates, steel pipes, etc., depending on the actual situation.
