1. Use the toilet dredge: insert the dredge into the toilet, press it down hard, then pull it up quickly, and repeat it several times until the blockage is removed.

2. Use hot water: pour some hot water into the toilet to raise the water temperature, and then wait a few minutes before flushing. Hot water can soften the poop and make it easier to pass through the pipe.

3. Use soap: Cut some soap into small pieces, put it in the toilet, and then pour in hot water. Soap can lubricate pipes and make it easier for feces to pass through.

4. Use the hook: insert the hook into the toilet, and then gently scrape the inner wall of the pipe until the blockage is removed.

5. Use gravity: pour some hot water into the toilet, and then flush it hard to make the water flow generate enough pressure to flush the blockage out of the pipeline.

If the above methods can't solve the problem, it is recommended to seek the help of professionals to avoid causing more harm.
