I just want to ask, are Hongdao people counted as Qingdao people?

If Hongdao people are not from Qingdao, then those who crossed Hisense overpass (north) before were not from Qingdao.

In fact, the vast majority of people in the third district of Qingdao are migrants around 49 years ago. What really has Qingdao's local characteristics are old villages such as Licun, Yan Jiashan, Yaos, Xinjiazhuang, Hudaozi and Wujiacun. A notable feature is accent, especially for the elderly, who are the same as the locals in Chengyang and Laoshan in Jimo, but different from those who immigrated around 49 years ago.

Of course, the official statement now is that the ID card 3702 starts.
