What do you mean my family has koi fish?
Koi fish, originally a kind of carp, was originally Cyprinus carpio, which is an ornamental fish. Before the Internet age, carp has been endowed with many connotations in the real history of China.
Liu Xiang in the Western Han Dynasty recorded the legend that carp was manned to heaven and became immortal, and took carp as a sacred mountain. In the Eastern Han Dynasty, the story of Yuelongmen was circulated. In the Tang Dynasty, the word koi fish appeared in the poem. "Although koi fish was ashamed to wear his forehead, he won the Dragon Ball." The same year after Huang Tao became famous. Koi fish in the poem is generally regarded as "the glistening carp", not the modern koi fish we see. Modern koi fish was born in Japan in the19th century, and its ancestor was China carp. Although modern koi fish has a history of only one hundred years in China, "koi fish" has been endowed with a symbol of beauty and wealth by modern China people because of its unique masculine beauty, longevity and prosperous geomantic omen and the beautiful implication of carp from China.
