Extended information
The story of "Carp Leaping over the Dragon Gate" was officially recorded in "San Qin Ji" written by Xin of the Han Dynasty (the book has been lost). According to the texts quoted in "Yi Wen Lei Ju" and "Taiping Guang Ji", the legend of "Fish Leaping over the Dragon Gate" was mentioned many times in "San Qin Ji". For example: "There is a dragon gate in Hejin. The water is impassable, and no fish or turtle can get up there. Thousands of big fish from the rivers and seas can't get up to the dragon gate. The one who goes up is a dragon." "There is a yellow carp that goes upstream, and the one who gets it will get it." Transformed into a dragon."
There is a description of "Longmen Chihe" in "Bamboo Chronicles". Every spring, large numbers of sturgeons swim back to Longmen Cave to gather and jump frequently in the two or three days before spawning. When the sturgeon jumped out of the water, its engorged and red fins also emerged from the water. For a time, thousands of big fish were flipping on the river surface, and a red light appeared in the distance. This is the "Longmen Red River". Because there are many fish, the fish can reach several miles, and can also last for several days, so there are also sayings in ancient books "Three Days on the Red River" and "Three Miles on the Red River".
The "carp" mentioned in "Carp Leaping over the Dragon Gate" is actually "tuna" or "snake fish", and the netherworld "carp" or "anchovy" is also a sturgeon. Sturgeon is a fish that migrates from rivers and seas, with a body length of about 2 meters and a maximum length of 5 meters. Since the big carp in ancient times was also called "鳣", the ancients mixed "tuna" with the big carp, and it was said that "carp leaps over the dragon's gate".
