3. The function of the flying sand weir is that when the water in Neijiang exceeds the upper limit of the bottle mouth, the excess water will automatically overflow from the flying sand weir; In case of serious flood, it will burst its banks by itself, so that a large number of rivers will return to the positive flow of Minjiang River. Another function is "flying sand". The Minjiang River runs down from Wanshan Mountain, carrying a lot of sediment and stones. If it is allowed to flow down the inner river, it will block the bottle mouth and irrigation area. Flying sand weir is really considerate and difficult, which will bring sediment and pebbles from the upstream, even boulders weighing 1000 kg.

4. After Qin unified the six countries, Meng Tian, the great star of Qin Shihuang, sent people to the northern expedition to Xiongnu, connecting the Great Walls of various countries, stretching for more than 10,000 miles from Lintao in the west to Liaodong in the east, hence the name "Wan Li Great Wall". There are only relics left in Qin Changcheng. Qin Shihuang built the Great Wall with 300,000 people, which created a miracle in the history of human architecture. The construction of the Great Wall has objectively played a positive role in preventing the Huns from invading the south and protecting the economic and cultural development of the Central Plains.

After 1977, archaeologists excavated the ruins of two small towns, one east and one west, in the ruins of Xia Dynasty, about15km southeast of Wang Chenggang, Dengfeng County, Henan Province, and found some precious written materials of Xia Dynasty. For example, in an ash pit at the site of Xicheng, a mud-black pottery flat bottom with the word ""on the bottom was found in early summer. This may be the word "* * *", which may represent the surname of the owner of the pottery. This word is not only a symbol, but also beyond the hieroglyphic stage, so it is a real word. This discovery strongly proves that as early as 4,000 years ago, China had written characters in the early Xia Dynasty.
