I remember the beginning of that issue of I Love Inventions: "An old man once fished in a reservoir and caught a big fish weighing 19 kg. As a result, he was turned millions of times, not because the fish was big, but because of his "invention". This is a fish hook with a bait hook. Bait hook is specially used for bait, and the hook is specially used for fishing, but the fish does not unhook. Then the reporter asked to see the new hook. They put a lot of fish in the fish tank and let him fish with a hook. Only one fish was fooled for a while. The reporter was very surprised, because no fish can escape this hook, which is simply a "lifeless hook"! The reporter asked him to compare with the traditional fishing method and scored 2∶3. Later, the inventor improved the hook. He made a solid lead pendant into a hollow lead pendant, and even if he sucked a small amount of fish, he could bite the hook. Finally, a man-machine contest was held, and the new hook completely defeated the old one.
This invention tells us that we must have bold imagination and diligent hands-on ability to create everything.
