Generally, people use white rabbits, scales, national squares, road signs, etc. Each has its advantages and disadvantages. What I know is that the White Rabbit system has been around for a long time, has good stability, and is a big brand that everyone knows. However, graphics retrieval is extremely slow, and updates are not very fast. The scale is from the last one or two years. It has many functions, is updated quickly, and can be searched, but the time is a bit short. I don’t think the search by the Chinese side is very good. They mainly do trademark status and monitoring, but they charge separately and the price is higher. We wanted to give it a try, so we changed from the white rabbit to the scale. As for the road signs, we didn’t know much about them because we had never used them before.
