"Salmo" is the Latin root of salmon (English salmon), and its original meaning is "jumping".
Due to the habit of salmon, they will travel upstream from the ocean along the river and return to the water source where they were born to incubate the next generation.
Even though the process of upstream swimming is full of various unfavorable natural enemies, natural disasters, etc., it is often necessary to jump into a waterfall nearly one meter high.
But they only have the cleanest upstream water source and the source of life in their hearts, and the others are not so important.
