So we started brainstorming ideas together. Anxious and worried, I looked around the pond, hoping to find something to help. Dad looked at his phone to find relevant case online. Suddenly, Mom came up with an idea, saying how about designing a simple device to keep a hole open. Encouraged and inspired by her words, Dad said what materials could be used to make it, and I then immediately picked up a bottle cut with a hole. In order to make the device, carrying a bottle of water, I tried many times. Tired as we were, we still kept building the bottle into the pond. A few hours witnessed our hard work.

By nine o'clock, we had built a simple device to keep a hole in the ice. So excited that I replaced it to the pond, which used the flowing water to keep a hole open. With the device, the fish gradually got more power to run. At the sight of them, I felt more guilt because I did not think more about them. The moment I watched the fish, the heart arrived. No sooner had I opened it than that day helped me install it to the pond. After a few minutes, the pond water flowed and the fish ran fast, floating like umbrella like before. I sighed with relief, and a sense of joy welling up in my heart. It dawned on me that every problem could be solved with effort. The pond was lively again.
