Shahe City had a long history of development. During the Spring and Autumn Period, this area belonged to the Xing State, then the Wei State; during the Warring States Period, it became the territory of the Zhao State; during the Qin Dynasty, it belonged to the Xindu County of Handan Prefecture. In the Western Han Dynasty, Xiangguo County was established here, belonging to the Zhao State of Jizhou. In the Eastern Han Dynasty, Xiangguo County was originally the Zhao State of Jizhou, and in the 17th year of Jian 'an, it was transferred to Wei County of Jizhou.

In the Jin Dynasty, Xiangguo County belonged to Guangping County of Sizhou, and later became Ren County. In the 20th year of Taihe of the Northern Wei Dynasty, Xiangguo County was re-established and moved to Xingtai City. After the establishment of the Sui Dynasty, Xiangguo County was initially the administration and territory of Xiangguo County, and later renamed Longgang County. In the 16th year of Emperor Kaihuang of Sui Dynasty (596 AD), Shahe County was set up in the south of Longgang County, Xingzhou. It was named after the Dasha River that passed through it. At that time, the old city was one kilometer east of the county. Shahe County belonged to Xingzhou and had a history of more than 1400 years. In the first year of Wude of Tang Dynasty (AD 618), Shahe County was established as Wenzhou, which belonged to Xingzhou General Manager Office. In the fourth year of Wude, it was restored to Shahe County, which belonged to Xingzhou.

In the first year of Hongwu of Ming Dynasty, Shunde Road was restored to Shunde Prefecture, and Shahe was one of the nine counties of Shunde Prefecture. In Qing Dynasty, Shahe County belonged to Shunde Prefecture of Zhili Province. During the period of the Republic of China, its subordinate relationship was also adjusted many times. For example, in the second year of the Republic of China, it belonged to Jinan Road, and in the following year, it was changed to Daming Road. In 1928, it belonged to Hebei Province. In 1937, after the fall of Hebei, the puppet North China Committee set up Shunde Road to govern 15 counties such as Shahe.

"God in My Home" was an ancient romance novel written by the author, King of the Mortal Realm. It told the story of a new book,"Return to the Origin". Those who want to teach me a lesson, please leave. The new book is in the form of a unit drama, so I'm not afraid of eunuchs! (No, no, no, that's not right. I'm trying my best not to be a eunuch…)<br><br>"Even if we're in different planes and live at different times, we'll still meet again and still be unable to break free from the fetters.

Although it was draped in the skin of a female channel, it was all kinds of hot-blooded martial arts and fantasy combat style! The author's greatest advantage was that every character in the book was well portrayed and could stand up. The female lead was a strong and unpretentious girl, and the male lead and the second male lead were both lovable! Even the supporting roles were very vivid! Then the question was, between the male lead and the second male lead, which one would the female lead choose? This was probably an unsolved problem.

If the symptoms of nausea and nausea after eating were relatively mild, they could be treated with drugs that promoted gastric mobility, such as domperitong and mosapride. These drugs could improve the function of esophagus squirming, enhance the movement of the digestive tract, promote digestion and absorption of the intestine, and improve the symptoms of indigestion. For patients with severe nausea and nausea, they could be treated with anti-acid drugs such as omeprazol and ranitidine, which could suppress the secretion of gastric acid and effectively improve the symptoms of nausea and nausea. At the same time, it also had a good treatment effect for diseases such as chronic inflammation, acute inflammation, and digestive ulcers. If it was because of the nausea and nausea after eating due to the Duodenal Ulcer caused by H. Pylori infection, a four-drug therapy could be used, which was a drug that inhibited gastric acid secretion (such as ilaprazol enteric-coated tablets), a protective agent for the gastric membrane, and two antibiotics. In addition, taking esomeprazole-magnesite enteric-coated tablets, sucralfate suspension, and Mopril tablets together may also have a good effect on the treatment of nausea and nausea. Specifically, esomeprazole-magnesite enteric-coated tablets were used for acid suppression treatment, one tablet at a time, twice a day, and taken half an hour before meals in the morning and evening. The sucralfate suspension neutralized gastric acid and absorbed digestive juice and bile, one pack at a time, twice a day, and was taken before breakfast and before bed.
