Ji–Lu or Jilu Mandarin (simplified Chinese: 冀鲁官话; traditional Chinese: 冀魯官話; pinyin: jìlǔguānhuà), formerly known as Beifang Mandarin 'Northern Mandarin', is a primary Mandarin dialect spoken in the Chinese provinces of Hebei and Shandong. Its name is a combination of the abbreviated names of the two provinces, which derive from ancient local provinces.
Although these areas are near Beijing, Jilu has a different accent and many lexical differences from the Beijing dialect, which is the basis for Standard Chinese, the official national language. There are three dialect groups, Bao-Tang, Shi-Ji, and Cang-Hui.
Dialect groups 
The Bao–Tang dialect shares the same tonal evolution of the inner tone from Middle Chinese as Beijing Mandarin and Northeastern Mandarin. Moreover, the popularization of Standard Chinese in the two provincial capitals has induced changes in the Shi–Ji dialect causing the former to shift rapidly towards the standard language.
