The S&P cause of the standard pronunciation of putonghua.

Why is the Putonghua in Luanping County, Chengde City, Hebei Province so standard? Wang Guoping told the reporter about a period of history he knew. According to historical records, in the early Ming Dynasty, due to the war, all the residents of Luanping County outside the Great Wall moved to Baoding, Hebei Province and Fangshan, Beijing, forming a "no man's land". This state lasted for about 200 years, and the traditional dialect completely disappeared.

"Later, the Qing soldiers entered the customs, and the princes and ministers and the Eight Banners troops moved from Gyeonggi and other places constituted the main body of the Luanping people. These people were influenced by the' Beijing Mandarin' at that time, and their pronunciation was naturally unified. " Wang Guoping said that Luanping dialect in Chengde City was handed down in the Qing Dynasty, which is characterized by clear intonation, which is a little harder than that of Beijing dialect, especially without ending, direct, clear and definite, and very close to Mandarin.

During the reign of Emperor Chengzu in the Ming Dynasty, all the villagers in Luanping County moved to Baoding, Yuxian and Fangshan in Beijing. After the Qing dynasty entered the customs, Dourgen began to implement the enclosure order, which was abolished in the eighth year of Kangxi. The relocated people moved from Beijing and other places to Gubeikou, and 24 villages were built in Luanping, including five imperial palaces, eight palaces and 24 Huang Zhuang, all of which were located here and were greatly influenced by Mandarin, so 60% of Luanping County was Manchu.

According to Wang Guoping, in 1955, the State formally established the State Language Committee to formulate the language plan. At that time, the name was Putonghua, and then the concept of Putonghua came into being. The formal plan was formulated in 1957 and officially announced in 1958.

In this scheme, we refer to the achievements of experts in collecting languages in Beijing Mandarin District to a great extent. The main collection locations are Jingoutun Village, Bakeying and Huodushan. Among them, Jingoutun is the most widely used language, that is to say, the pronunciation and vocabulary collected by Jingoutun at that time are the closest to Mandarin. Wang Guoping said that every few years, the Hebei Provincial Language and Literature Working Committee will go to this area for inspection and acceptance of Putonghua.
