Why is there an elephant sign on the sign of Henan Expressway?

According to the traffic broadcast of Henan Radio and Television Station, the symbol "G300 1" on the "Elephant" stands for the highway number, followed by "22B" which is the specific number of the gantry, and the letter B generally stands for the downward direction. The elephant on it is only because it is a symbol of Henan. In order to make this signboard more eye-catching, the pattern of "elephant" was added.

There are many connections between Henan and Henan. Henan is named because most of the area is located in the south of the Yellow River. Henan is one of the Kyushu divided by Dayu after flood control in ancient times. The Central Plains is called Yuzhou, and the scope of Yuzhou is basically the same as that of today's Henan Province. The original meaning of the word Yu is peace and happiness. Dayu named it Yuzhou, probably because he felt comfortable here, and it was also his birthplace and hometown.
