According to ancient records, there is indeed a frog named frog in Northeast China. But now there is no such name in Northeast China. It is unknown whether outsiders at that time could not tell the difference between frogs and forest frogs, and it is still unknown whether they were dubbed common names at first sight.
Frog is a popular name for frogs within the Great Wall. The object is generally a frog called tiger frog or black frog, which is what we generally call frog.
