What is it that Qingdao people don't speak Shandong dialect?

The reason why Qingdao people don't speak Shandong dialect is very simple. But many friends don't know, so I will tell you here to avoid any misunderstanding in the future. Explain it culturally first. The concept of Shandong has always been a province established by the rulers for the convenience of management. This vast land has been two different countries since ancient times. Qi in Jiaodong Peninsula and Lu in the interior. The cultures and customs of the two places have been very different since ancient times. Qi is a marine civilization dominated by industry and commerce, while Lu is a continental civilization dominated by farming. Each has its own characteristics. Today, this feature can still be found in the personalities of the two places. From the linguistic point of view, Shandong dialect refers to the dialect in Luxi area represented by Jinan dialect, belonging to a certain area of Jilu Mandarin whose name I don't know. I couldn't tell its characteristics clearly, so I ran to Jinan Street and pulled it myself. Pan-Qingdao area speaks Jiaoliao Mandarin, and I can't tell the characteristics clearly. Probably the dialect of Jimo Jiaozhou and other places around Qingdao. Including Weifang, Yantai, Weihai and other places, it is also Jiaoliao Mandarin, but the areas are different. Friends in these places should find out their cultural roots and language sources, and don't ask others what you are talking about when going out. You say it's Shandong dialect, and then ask someone to tell a joke. What you said is Jiaodong dialect. By Qingdao people here, I mean the earliest people in old Qingdao (from Tuandao East to Zhanshan South to Haibin North to Sifang), and what they said is not Jiaoliao Mandarin. Qingdao is an immigrant city. Among the first batch of China people who came to Qingdao (Qingdao refers to Qingdao after the German city was built, not today's Pan-Qingdao area), there were old people and young people in Manchu, landlords and gentry in Shandong, entrepreneurs from all over the country, laborers from all over the country, refugees fleeing from the countryside and farmers in Pan-Qingdao area. These people are the ancestors of people in the old city of Qingdao today. They have different accents and live in this new city with German expatriates and later Japanese expatriates. Gradually, in order to facilitate communication, after their languages merged with each other, our Qingdao dialect appeared today. Qingdao dialect is dominated by northern mandarin, which has many characteristics of Jiaodong dialect, vocabulary and pronunciation characteristics of southern dialect, and some loanwords from Germany and Japan. Qingdao dialect is not widely used, and it is basically only used in South, North and sifang district. Therefore, the old Qingdao people speak neither Shandong dialect nor Jiaodong dialect, but Qingdao dialect. I don't know if this explanation is thorough enough, but the general idea is that some details may be inaccurate, and there is nothing I can do. I am not a linguist. Just as a child in Qingdao, I don't want to be misunderstood.
