Qiantang bore-the most spectacular tide.

Edit the introduction of this paragraph.

In the history of our country, there are three famous tidal bore: Qingzhou tidal bore, Guanglingtao tidal bore and qiantang bore tidal bore.

Qing Feihuan (1664- ...) "Argument on Guangling Pottery" says: "In the Spring and Autumn Period, the tide in Shandong flourished, and Guangling flourished in the Han, Wei and Six Dynasties. After the Tang and Song Dynasties, the tides in Zhejiang rose and fell, and the atmosphere was from north to south, and people of insight. "

Qiantang hole appeared later than Guangling pottery and was formed at the latest in the Eastern Han Dynasty. Wang Chong's Lun Heng Xu Shu mentioned that "Zhejiang, Henan and Shangyu rivers all have their own paths". He also said that Qiantang Zhejiang "all set up Zixu Temple to comfort their grievances and stop their violent waves". However, Wang Chong only said that "there are pottery in Qujiang, Guangling, and literati endowed it", but did not say that Qiantang River was endowed with tide. It can be seen that in the Eastern Han Dynasty, the fame of Qiantang Hole was far less than that of Guanglingtao. It is estimated that the custom of watching tide in Qiantang was not formed at that time.

Edit the reason of Qian Jiangchao in this paragraph.

Time: On the 18th day of the eighth lunar month, the sun, the moon and the earth are almost in a straight line, so the most attractive thing is the sea.

Geographical location: It is related to the trumpet-shaped estuary of Qiantang River. Nearly 500,000 mu of land was reclaimed to the east of Zheshan Mountain on the south bank of Qiantang River, which blocked the estuary like a peninsula, making the section from Zheshan Mountain to Qiantang River 12 like a small belly bottle, which is easy to retreat when the tide rises. The width of the outer mouth of Hangzhou Bay is 100 km, which is only a few kilometers away from the outer 12 section. The riverbed in the eastern part of the estuary suddenly rises and the beach is shallow. When a large number of tides flood in from the mouth of Qiantang River, it is difficult for the river to retreat because of the rapid contraction of the river surface. Secondly, it is related to the sediment deposition under the Qiantang River. These sediment deposits act as a barrier and friction to the tidal current, making the slope of the tidal front steep and gentle, thus forming a wave to catch up with the previous wave, wave after wave, and wave after wave.

Wind direction: Southeast winds are often blown along the coastal areas of Zhejiang in summer and autumn, and the wind direction is generally consistent with the tidal direction, which is conducive to the tidal trend.

Edit this boring story of Qiantang.

When the Qiantang River is at high tide, like other rivers, there is neither tide nor sound.

One year, a giant came by the Qiantang River. The giant was so tall that he crossed from one side of the river to the other. He lives in Shushan, Xiaoshan County, and sets fire to salt. People don't know his name, because he lives by the Qiantang River, so they call him Qian Wang. Qian Wang has great strength. He often used his iron pole to pick some big stones and put them on the river. Soon, he piled up one mountain after another.

One day, he went to pick the salt he had burned in Shushan for three years and three months. However, the salt was only enough for him to hold one end, so he tied a big stone to the other end of the pole, tried it on his shoulder, and picked it up and crossed the north bank of the river.

It was hot at this time, and Qian Wang was a little tired because he had just had lunch, so he put down his burden and had a rest. Unexpectedly, he dozed off Just then the Dragon King of the East China Sea came out to patrol the river, and the tide came in. Up and up, even up to the shore, slowly melting all the salt on Qian Wang. When the Dragon King of the East China Sea heard that there was no such salty taste in the water, it became more and more salty. He couldn't take it anymore, so he turned around and ran away. He doesn't want to escape to the ocean and make the sea salty. King Qian slept, opened his eyes and found that the stone at one end of the pole was still on Shixia Mountain (now Shixia Mountain), but the salt at the other end was gone!

Qian Wang looked everywhere, but he couldn't find salt. As soon as he looked down, he smelled the salty taste in the river. He thought, oh, no wonder the salt is gone. Stolen by the East China Sea Dragon King. So he raised his pole and smashed it into the sea. A pole hit the big fish and they all died; Two poles turned over at the bottom of the river; The three poles brought the Dragon King of the East China Sea to the surface, begging for mercy.

The Dragon King of the East China Sea asked Qian Wang why he lost such a big temper. Qian said, "Where did you steal my salt?" The Dragon King of the East China Sea realized the reason why the seawater became salty. Make amends at once, and tell me how to patrol the river, how to melt the salt of Qian Wang unintentionally, and make the sea water salty.

The king of money was so angry that he really wanted to lift the iron pole and smash the dragon king of the East China Sea to death. The Dragon King of the East China Sea repeatedly kowtowed in panic and begged for mercy, promising to compensate Qian Wang with the salt in the seawater. Call it up when the tide rises in the future, so that the rich king won't fall asleep and can't hear it. Hearing that these two conditions were not bad, Qian Wang spared the Dragon King of the East China Sea, put the pole at the mouth of Hangzhou Bay and said, "Call from here when the tide is high!" The Dragon King of the East China Sea promised again and again, and the money king left happily.

From then on, as soon as the tide entered Hangzhou Bay, it stretched out its neck and cried noisily until it rose to the place where Qian Wang had sat, and its neck stretched out to the top and shouted loudly. This place is now Haining. This is the origin of the world-famous Qian Jiangchao.

Edit this paragraph, Wu Zixu, the tide god.

Wu Zixu (? -484 BC) Doctor Wu in the Spring and Autumn Period. Xu, a famous courtier, is the second son of Wu She, a doctor of Chu State. King Chu Ping abandoned the Prince's Tower in seven years (522 BC) because he was fatuous and listened to rumors, and killed his master Wu She and his eldest son Wu Shang. Wu Zixu quickly fled from Chu State, wandered in Zhaoguan (now northwest of hanshan county, Anhui Province), crossed the Yangtze River and entered the increasingly powerful rival Wu State of Chu.

Wu Zixu devoted himself to the wide door of Wu. In the 12th year of Liao Dynasty (5 15 BC), Zhuan Xu, a strong man recommended by him, assassinated Wu Wangliao and helped the son regain the throne, calling him Prince and Lu. Wu Zixu then sought national politics, "set up a city wall, set up a garrison and take charge of Hyogo", and built a big city in Harmony. Since then, Suzhou has become the capital of Wu in the Spring and Autumn Period. Wu Zixu also dug a wide and deep canal and built five dams hundreds of miles east of Gaochun to harness the landscape. It is not only beneficial to agricultural irrigation, but also a convenient transportation waterway when entering Chu. This canal is called "Xu Xi" and "Xu He".

After Wu Zixu and Sun Wuzhen's army fought, they conquered the capital of Chu in the ninth year of He Lv (506 BC), which made King Chu of Zhao flee (King Chu Ping died in 5 16 BC). Wu Zixu is also known as Xu Shen because of his work. In the first year of Focha (495 BC), Daxing Water Conservancy, a canal that Wu Zixu connected Gao Hui, Gugang and Chu Shi, was called Xupu, which reduced floods and made the economy prosperous. Wu Zixu was finally alienated by persuading Fu Cha to reject the peace in Vietnam and urging it to stop cutting Qi. So that in the twelfth year of Focha (484 BC), he was killed by Focha and thrown into the river. The people of Wu revered his loyalty and regarded him as a tide god. Wu Zixu Temple and Xuwang Temple were built in the past dynasties, and tombs were built for sacrifice. Now the temple is destroyed and the tomb is rebuilt.

Edit the characteristics of Qiantang hole in this section.

Cross tide

55 kilometers away from Hangzhou Bay, there is a place called Daguan, which is an excellent place to watch the tide. Due to the long-term deposition of sediment, a sandbar is formed in the river channel, which divides the tidal wave from Hangzhou Bay into two waves: the east tide and the south tide. After bypassing the sandbar, the two tidal heads crossed and embraced like two brothers, forming a varied and spectacular cross tide, showing a spectacular scene of "thunder gathering on the sea and waterfalls crossing the river". At the moment when the two tides collided, a water column was stirred up, which was as high as several feet, splashing and stirring. By the time the water column fell back into the river, there were already two tidal heads on the river, which were cross-shaped and quickly ran west. At the same time, the intersection moved northward like an avalanche, hitting the straight seawall, causing huge splash and landing on the top of the pond, scaring tide watchers to scream and avoid.

Yixianchao

After seeing the tide crossing in the Great Gorge, I suggest you drive to Yan Guan as soon as possible and wait for the first tide. No tide shadow, smell the tide first. There was a loud noise in my ear, and the river remained calm. The noise is getting louder and louder, like drumming on all sides, which is deafening. In the distance, a white line appeared on the foggy river, which moved rapidly to the west, just like "Pingchuan crossing the river, Changpingsha starting from Bai Hong". Closer, the white line becomes a water retaining wall and gradually rises. "If you want to know how high the tide is, you must cross the mountains and waves first." With the rapid advance of a white wall, the tidal bore came to our eyes. With the trend of Ma Benteng, the power of thunder was unstoppable.

The first-line tide is not unique to salt officials. Where the river is straight and there is no sand, the tides are all on the same line, but it is not as good as the salt official. The reason is that the position of the upstream Yan Guan and the width of the river channel shrink sharply, and the east and south tides meet in a straight line, so the tidal level energy is concentrated, and the tidal range is particularly large, usually 1-2 meters, and sometimes it can reach more than 3 meters. Magnificent and spectacular tidal scene.

Huitouchao

The tide in the upper reaches of Yanguan will reach the next tidal spot, Laoyancang. The geographical environment of the old salt warehouse is different from that of the dry salt official. The river is straight and the tidal bore advances westward without any obstacles. For the purpose of reclamation and seawall protection, a 660-meter-long groin was built on the river course of the old salt warehouse. After encountering obstacles, the roaring tide will be reflected and turned back, where it will violently hit the opposite dam, and then turn back with the trend of Mount Tai topping, and fall on the rapids moving westward, forming a row of "snow mountains".

The spring tide of Qiantang River is magnificent during the day and poetic at night. Watching the tide is a kind of enjoyment, and listening to the tide is a daydream. No wonder some people say that "the Qiantang national ceremony is not enough to see the hipsters until they are bald."
