This is the stop where Shanshan loves life, photography, travel and food.

Ask many people who have been to Guangzhou, what is their impression of this city? Many people will think that Guangzhou is an international metropolis: bustling, high-rise buildings, fashion, charm and so on. When you travel to Guangzhou, you can see the city scenery of skyscrapers, travel around the mountains and feel the history and culture of Guangzhou, but will anyone associate Guangzhou with the "vast sea"? Have you ever wondered what Guangzhou was like 5000 years ago or earlier? Want to know this, Shanshan Sanyou recommended that you might as well come to Guangzhou's "Qixinggang Ancient Coastal Relics", which is known as the "world's first ancient coastal relic", and feel this place that has witnessed the vicissitudes of Guangzhou for thousands of years.

On this day, Shanshan Sanjiao visited Guangzhou Qixinggang Ancient Haiyan Site Science and Technology Park, which is located at the northwest of the intersection of Shiliugang Road and South China Expressway in Guangzhou, and can be reached directly by bus. You can also take the bus to "Xinjiao East Road Central Station" and then go to Shiliugang Road.

Many years ago, the ancient sea salt site in Qixinggang, Guangzhou had not yet been built into a park, but was just a dark brown reef wall. Even Lao Guang, who has lived in Guangzhou for many years, and even people who pass by every day, probably few people know that this is "the world's first ancient coastal site". In fact, 1963 was designated as the first batch of cultural relics protection units in Guangzhou, with walls and pavilions. Later, it was recognized as a geological relic of sea cliff landform, which was protected by the highest level of national first-class protection, but not many people really knew it. It cannot be said that this is the most "national treasure" scenic spot in Guangzhou. It was not until the establishment of Qixinggang Ancient Coast Ruins Park that people gradually realized that this scenic spot was not a beautiful scene, but a discovery with important special value.

Shanshan got off at Sanyatou and came to the gate of Guangzhou Qixinggang Ancient Haiyan Site Science Park. There is no need to buy tickets for the visit. As soon as you enter the gate, you can see the sign of "Guangzhou Qixinggang Ancient Haiyan Site Science and Technology Park" standing on the ground. On the right of the sign is the statue of Wu Shangshi, a famous geographer in China and a geography professor at Sun Yat-sen University. He is also the discoverer of the ancient coast site of Qixinggang.

Walking forward from the statue, you can see the ruins of the ancient coast of Qixinggang. It looks like a dark brown reef wall, because it is raining and there is water next to it. Guangzhou Qixinggang ancient coastal site is the longest known ancient coastal site in the world (up to 100 km), and it is also the physical evidence of the changes in Guangzhou and the Pearl River Delta, which is of great scientific significance for studying the natural environment changes in the Pearl River Delta.

The ancient coast site, also known as the "fossil coast", as a thrilling landscape, took millions of years of waves to form. The landform of Qixinggang ancient coastal site in front of us is quite peculiar, which is a kind of marine erosion landform. It consists of three parts: ocean cliff, ocean cave and ocean erosion platform. They were all formed under the action of wave erosion, indicating that at a certain period in history (estimated to be more than 5,000 years ago), the global temperature became warmer, the sea level rose, and the sea water once penetrated into Guangzhou. Most of Guangzhou is in a Wang Yang, and the vast sea is beating against the island shore, and the waves are eroding it.

Later, the sea began to slowly withdraw from Guangzhou. In Song Dynasty, Guangzhou was also called "Little Sea". Since the Ming Dynasty, the land and water areas of the Pearl River Delta began to change obviously, and the speed of return was obviously accelerated. By the time of Daoguang in Jiaqing, Qing Dynasty, the seawater had retreated to the south of Shunde, and then retreated at the rate of 70-130m per year. Due to the restriction and influence of the whole regional environment, 20 marine erosion sites have been discovered in the Pearl River Delta, except the Qixinggang ancient coastal site, so this ancient coastal site is of great significance to the study of land and sea changes and coastline changes in the Pearl River Delta region.

Before the discovery of the ancient coast site of Qixinggang, geographers generally regarded the "marine erosion site in the lower reaches of the Po River" 50 kilometers away from the Italian coast as the biggest milestone for the sea to retreat to the mainland. However, in 1937, Wu Shangshi, a famous geographer in China and a professor of geography at Sun Yat-sen University, discovered the ruins of the ancient coast of Qixinggang, breaking through the statement that the world's ancient coastline and today's coastline have a maximum width of 50 kilometers. Qixinggang ancient coast site is more than 0/00 kilometers away from the coast/kloc-,which is twice that of Italy. Therefore, geographers at home and abroad believe that the ancient sea relic of Qixinggang can be called a "world-class" and "national treasure" marine erosion relic, and it is the deepest ancient coastline discovered in the mainland so far.

From 65438 to 0996, at the 30th International Geological Congress, the Qixinggang Marine Erosion Site, as the starting point of the geological field investigation route in South China, received the top geologists from all over the world at that time and was affirmed and admired by scientists from all over the world.

The whole park is divided into five areas: site protection area, site display area, popular science supporting area, bridge bottom supporting area and park display supporting area. Shanshan Sanyatou observed all the way and walked on the highest peak of the hillside.

Standing on a high place, facing the wind, a thrilling picture emerges in my mind. Imagine the huge waves in ancient times, coming violently and leaving traces here. When countless years passed quietly, the sea under Qixinggang became a field, and the coastline moved southward 100 km. Qixinggang, an ancient hill, still stands silently in a corner of the city, telling people the story that happened here and silently watching the story that will happen here.
