According to Baidu's Chinese query, "The river runs down and pours into Wang Yang" comes from a poem in On young chinese, which means that the Yellow River rises from the ground and surges, symbolizing vitality and strength. Author Liang Qichao; Modern dynasties.
There is a poem: the red sun rises, and its path is bright. When a river comes down, it pours into Wang Yang. Dive into the depths of the dragon, scales flying. The milk tiger roars in the valley, and all the animals are surprised. The falcon tried its wings and the dust scattered. Strange flowers are born, and they are called emperors. Dry hands can make a difference, but they can also make a difference. The sky wears its gray and the earth wears its yellow. Even if there were years, there were eight famines. The future is like the sea, and there is plenty of time.
