What is the year of Wuchen in Qing Dynasty, a famous porcelain painter in Wuchen?

When was Chen Wunian in Qing Dynasty? As the saying goes, "Guilin's landscape is the best in the world, and Yangshuo's landscape is the best in the world." Under Meiren Peak in Yangshuo County, China, there is a rhinoceros lake with an area of 300 mu. The lake is clear and blue. Fish and crabs are swimming.

According to the old people in the village, the water rose once on March 17 (1868) and lasted for 4 days. On June 7, 2009 (1940), the water rose again. The weather was fine that day, and water suddenly came out of the hole. In an instant, the water rose to a foot deep, and in less than three days, the village and fields were covered with Wang Yang, just like Zeguo. At that time, it was the beginning of the early rice ripening season. Experienced villagers knew that the flood would not subside in a short time, and the villagers rushed to cut rice. It was a sensation, and people from all over the country came to see the flood.

However, on September 30th, 1987,/kloc-0, blue lagoon suddenly disappeared, leaving only the mud at the bottom of the lake. People are frightened to disgrace. According to local memories, a month ago, there was a "rumbling" sound in the ground near Rhino Lake, and the water level of the lake also dropped slightly, but the depth of the lake was still about 2 meters. 1On September 29th, 987, the lake suddenly disappeared. The rhinoceros lake disappeared in about 30 years, which was recorded in Yangshuo County annals.

So, what is the mystery of the strange phenomenon of life and death in the lake? According to the analysis of relevant people, there is an explanation at present: Guilin's landscape is all composed of soluble limestone, with dissolved columns, dissolved peak caves, dissolved lakes and underground rivers criss-crossing. Rhino Lake is surrounded by mountains and is a dissolved lake. The water in the lake falls from the ground, from the sky, and underground water. The river flows into the underground river through the dissolved holes at the bottom of the lake, and some water naturally evaporates and disappears. Whenever there is a rainstorm, the lake is blocked by a lot of sediment, and too much rain accumulated over the years can make up for the long-term backlog in the underground passage in the mountains and cannot flow into the underground river smoothly. The more water, the greater the pressure, and the drainage conditions of underground rivers are blocked. In this way, the accumulated water is affected by great pressure, and from the sudden discharge, the fountain phenomenon will suddenly appear. After a period of time, when the discharge speed is accelerated and the water quantity is insufficient, the pressure will gradually become normal, the underground river will be in a normal flow state, and the water will quickly return to the underground river and flow to the river.

The analysis shows that there is a new process of water accumulation and the coverage of dissolved holes at the bottom of the lake. Similarly, the pressure relief of water and the dredging of dissolved holes are gradual, and the whole process takes about 30 years to complete. Therefore, the fluctuation of rhinoceros lake is once every 30 years or so. Of course, this phenomenon is influenced by meteorology, surface and underground water flow, human activities and other factors, and its cycle is not absolute. Some people imagine that if the dissolved hole at the bottom of the lake is blocked, the lake may never disappear.

The phenomenon that Yangshuo Lake comes back to life and goes round and round is very intriguing. So far, scientists have not found the real reason for it, about 30 years. Therefore, Yangshuo Lake has become an unsolved mystery, which remains to be discussed.

The above is related to Chen Wunian in Qing Dynasty, and it is about the sharing of underground rivers. I hope this will be helpful to everyone after reading Wu New Year's famous porcelain paintings!
