Longmen ". According to "Famous Mountain", "When the river reaches this mountain, the water waves rise and fall, like a mountain boiling". Qing Qianlong's "Hancheng County Records" contains: "There are broken mountains and cliffs on both sides of the strait, which are relatively like doors, but dragons can cross them, so they are called Longmen. According to legend, "Longmen" was carved by Dayu when he was in charge of water control, also known as Yumendu. Regarding "Yu chisels the Longmen", Lv Chunqiu said: "Diligent in the world, unremitting day and night, connected with Dachuan, absolutely blocked, chiseled the Longmen. "Three Stories Meeting" records: "There are two mountain walls here, from which the river flows out, competing for about a hundred steps. The walls on both sides are cut off and shaped like doors, so it is called "Longmen".
A Fish Jumping over the Dragon Gate-Passed a Competitive Examination.
The Chinese myth and legend story of carp yue longmen was officially recorded in Xin's "Three" in Han Dynasty. This book has been lost. According to the quotations from this book by later generations, such as Yiwen Lei Ju and Taiping Guangji, the legend of "Fish Jumping at the Dragon Gate" is mentioned in Sanqin Ji in many places. For example, "Hejin is the Longmen, the water hazard is impassable, and fish and turtles can't get on it." There are thousands of big fish in the river and sea under the Longmen, but they are dragons at the top. Another example is "Longmen Mountain is in the east of the river" ... Every spring, the yellow carp goes upstream and the winner is the dragon. "Wait a minute.
In fact, the mystery of "Carp yue longmen" can be solved by modern science: the carp here are actually "tuna" or "snakehead", also called "snakehead" or "yellow croaker", that is, sturgeon. Sturgeon is a migratory fish, with a body length of about two meters and a maximum length of more than five meters. China's rare animals, ACIPENSER sinensis, ACIPENSER northeast and ACIPENSER Changjiang, are all such fish. Because the ancient big carp was also called "gun", the ancients mixed the "gun" with the big carp and called it "carp yue longmen".
Sturgeon didn't come to Longmen to "leap the dragon", but to breed. The book "Study on Biology and Artificial Breeding of Acipenser Changjiang" written by Sichuan Yangtze River Aquatic Resources Investigation Team says: Acipenser Changjiang mostly lays eggs in the upper reaches of the river, with low water temperature, fast flow rate, complex flow pattern, wide and narrow channel and gravel bottom. The Longmen area at the junction of Shan State and Shan State has the above landform characteristics, so it has become an ideal place for sturgeons to gather and lay eggs.
