Everyone uses white rabbits, scales, countries, road signs, etc. Each has pros and cons. All I know is that the White Rabbit system has been running for a long time and its stability is okay. Everyone knows about big brands, but image and text retrieval is extremely slow and updates are not very fast. If the scale is within the last one or two years, it has many functions, updates and searches are fast, but the time is a bit short. I think Chinese search is not very good. What they mainly do is trademark status monitoring, but they charge separately and the price is higher. We wanted to try it, so we changed the white rabbit into a scale. As for the road signs, we don’t know much.
