Baotu Spring ranks first among the "72 famous springs" in Jinan, and is known as "the first spring in the world". Located in front of Luoyuan Hall in Baotu Spring Park, Jinan, Baotu Spring is the first spring in Jinan in ancient literature. In 2002, according to the textual research of Oracle Bone Inscriptions unearthed in Anyang, Henan, some experts found that Baotu Spring has a written history, which can be traced back to the Shang Dynasty in China as early as 3543. Baotu Spring is the source of ancient water, which was called Baotu Spring in ancient times, and was named Baotu Spring by Ceng Gong in Song Dynasty. There are also names such as Threshold Spring, Eying Water, Hot Springs, Waterfall Flowing Water and Water of Three Rivers. The so-called "Baotu Spring" means jumping and rushing, which embodies the characteristics of the third hole of Baotu Spring, which gushes endlessly. Li Daoyuan in the Northern Wei Dynasty wrote in the Notes on Water Classics: "Spring is blooming, and water is surging like a wheel." "The three caves are surging, the snow waves are several feet high, and the sound is like hidden thunder." Yuan Haowen, a poet in the Jin Dynasty, described it as "looking at the Jade Pagoda from the waves", while Zhao Mengfu, a famous painter and poet in the Yuan Dynasty, compared it to "a white jade pot gushing from the ground", and how did the poet in the Qing Dynasty describe it as "the beads are flying upside down"? In Liu E's Travels of Lao Can in Qing Dynasty, it was stated that "the three springs rose from the bottom of the pool to a height of two or three feet". Pu Songling, a famous writer in Licheng County, thought Baotu Spring was "the first spring in the world and the Qimen resort was unparalleled". Baotu spring water gushes from underground limestone caves, with a maximum inflow of 240,000 cubic meters per day and an exposed elevation of 26.49 meters. The water is crystal clear, the water quality is mellow and sweet, and the bacterial content is extremely low. After testing, it meets the national drinking water standard, is an ideal natural drinking water, and can be directly drunk. "Flying" is the first of the eight scenic spots in Jinan in Ming and Qing Dynasties. The spring water is kept at around 18 degrees Celsius all the year round. In winter, the water vapor curled up like a thin layer of smoke. On the one hand, the spring pool is deep and sparkling, and on the other hand, the pavilions are picturesque and beautifully carved, which constitutes a wonderful fairyland on earth. Locals call it "cloud steaming and fog moistening". Baotu Spring is an ideal drinking water with clear and transparent water quality and sweet taste. According to legend, Emperor Qianlong went down to the south of the Yangtze River and took Yuquan water from Beijing when he left Beijing. After he tasted Baotu spring water in Jinan, he immediately changed to Baotu spring water and named Baotu spring "the first spring in the world". The spring is in Fangchi, facing Luoyuan Hall in the north, Guanlan Pavilion in the west, Xianhe Bridge in the east and a promenade in the south, with excellent scenery. There are goldfish in the spring pool, and the biggest one is more than three feet long. On the east side of the spring, opposite the crane bridge, Heting Tea House is expected to provide tourists with fragrant teas brewed with Baotu spring water.

geographical position

Baotu Spring originates from Taiyi Pool in Wuwangshan Mountain and is an inexhaustible source of water. Pu Songling, a writer in Qing Dynasty, said at the beginning of Baotu Spring Fu: "The source of dragon water originated from the king of Wu; For the sake of the economy, it will fall when you see it; Down to Jimen is a great blasphemy; Go through the city and travel all over the country. " Li Daoyuan's Notes on Water Classics in the Northern Wei Dynasty described the topography and flow direction of Jishui in detail, especially the spring lake landform formed by Baotu Spring and Daming Lake in the south of Jishui. Baotu Spring has attracted more and more attention from the world, and it has the reputation of "you can't travel without Baotu Spring in Jinan". Baotu Spring has been rated as one of the top ten national excellent gardens, "Top Ten" parks and national 4A-level scenic spots, and it is the first batch of national key parks.

Dutch windmill-history

Long ago, Holland in western Europe was covered with virgin forests and swamp trees. A vivid description is that until 1000 years ago, a squirrel "ran" from one place to another far away, not on the ground, but on the top of a tree. The Netherlands near the North Sea is a "low-lying country" with many swamps and lakes, and a lot of land is 6 meters below sea level. For example, today's Amsterdam International Airport is located about 4 meters below the sea level in the North Sea. Therefore, the Dutch story is nothing more than the legend of man and nature: windmills, wooden shoes, cheese and tulips. Because of the low terrain, the Netherlands is always facing the erosion of the tide, and the instinct to survive gives the Dutch motivation. They built dams and dikes in the sea to compete for land, built pumping windmills as high as 9 meters, and created living homes. 1229, the Dutch invented the world's first windmill to provide power for human beings. For a long time, people used primitive methods to process and grind grains, first by hand, then by horse-drawn treadmills and water-driven waterwheels, and then by windmills. Because the Netherlands is flat and windy, windmills quickly became popular. The rapid growth of demand has led to the change of windmill technology. The use of windmills is no longer limited to grinding grains, but has developed to processing barley, sawing logs into beams and boards, making paper, squeezing oil from various oil crops such as flaxseed and rapeseed, and grinding spices into mustard. Although it has many uses, people prefer to remember this old European proverb: "God created man, and the Dutch windmill created land." Indeed, without these towering pumping windmills, nearly one-third of the land in the Netherlands could not have come from the sea, nor would it have the fragrance of cheese and tulips later.
