Carp Leaping Dragon Gate is a metaphor for professionalism, hard work, daring to think, daring to do, daring to build a dream. After the introduction of the imperial examination system, fish leaping over the Dragon Gate was used as a metaphor for winning the imperial examination, so the Dragon Gate has a sacred status in the hearts of the people.

Legend:

According to legend, after Yu opened the Yiquet, the water flowed swiftly, and the carp in the Yellow River in Mengjin (now under the jurisdiction of the county of Luoyang) swam down the water of Luoyang and Yiquet against the flow, and when they swam to Yiquet, Longmen Gate (where the Longmen Grottoes are located in Luoyang), the waves were so strong that they jumped, wanting to go over.

Those who jumped were dragons, and those who did not jump left a black scar on their foreheads, which is why Li Bai, a great poet of the Tang Dynasty, wrote in his poem "Gift to Cui", "Three-foot carp in the Yellow River, which resided in Mengjin, and which did not become dragons, returned to accompany the ordinary fish.

Since then, in the late spring, countless golden carp would swim upstream along the Yellow River and gather under the Yu Gate, jumping vigorously, and the occasional one that leapt over the gate would be transformed into a dragon, soaring into the nine heavens above. The Yumen Gate, where the dragon soars, is called the "Dragon Gate", which means "one leap and you are worth a hundred times more".

The allusion to "Carp leaping over the Dragon Gate" is often expressed by the arowana fish with a dragon's head and a fish's body. This wall shows the carp spitting under the Dragon Gate in the rolling waves of the river, and the arowana leaping over the Dragon Gate to become a dragon, spreading its wings and wanting to fly to the sky.
