The meanings of Wen Kaijiang and Wu Kaijiang are as follows:
Wu Kaijiang: It is a dialect of the Guandong region. It refers to the ice layer bursting on the frozen river surface due to the sudden warming of the climate, and the ice blocks accumulate and overlap. The originally quiet river surface will suddenly make a thunderous sound, and the ice on the river will suddenly bulge and immediately break into countless ice cubes. The ice cubes will be unable to flow down the water for a while, and will be rushed to the beach, forming an ice dam, just like a glacier. collapse.
We often encounter strong winds, and under the turbulent river water, huge ice blocks collide together, roaring like thunder. Under the impact of icebergs and roaring rivers, ships, pedestrians, houses, buildings, etc. on the shore will be destroyed in an instant.
Wenkaijiang: refers to the gentle and gradual melting of the ice on the river. The unmelted ice floes are carried by the undulating river water and drift downstream. Small ice sheets are often struck on the river. . Due to the sudden rise in temperature, the ice on the frozen river exploded and the ice cubes overlapped. The rear row of ice rows on the river pushed the front row down the river. The roaring river water carried the ice cubes and rolled up and down, and the huge ice rows collided with each other. , sometimes the ice is pushed up to the embankment more than ten meters away.
Some are several meters high, and the huge roar caused by the collision of ice sheets can be heard several miles away from the river bank. If the temperature changes slowly, the ice on the river surface will slowly melt, and the ice rows will flow in an orderly manner, relatively slowly and quietly, which is the "Wenkai River".
The so-called Kaijiang: It refers to the late autumn and early winter in cold areas. The river surface gradually freezes and freezes. The ice is so solid that pedestrians, cars and horses can travel on it. After the Qingming Festival, the ice and snow melt, and the ice on the river either quietly "opens" or suddenly "opens". In any case, the ice layer cracks and disintegrates due to phenology, exposing a river of spring water, which is called "opening the river".
