Where does the Jiaodong Gang refer to, including Qingzhou people?

Shandong Peninsula, also known as Shandong Peninsula, is located in the east of Jiaolai Valley, Shandong Province, China, surrounded by the sea on three sides. It has a pleasant climate and four distinct seasons. Due to the influence of the ocean, compared with the inland at the same latitude, the climate is mild, with no heat in summer, no cold in winter, small temperature difference, mild winter and no heat in summer. 1 month, the average temperature is above 0℃, and the average temperature in July is 25℃. Main climatic characteristics of Jiaodong Peninsula: in terms of temperature, the western part of the Peninsula is higher than the eastern part, the northern part is higher than the southern part, and the coastal part is higher than the inland part, including Weihai, Yantai, Laizhou, Pingdu, Penglai, Longkou, Qingdao and Rizhao. The annual average temperature is 12.0- 12.6℃. There is more precipitation in the east, and less precipitation in the west: Dazeshan, Laizhou, Longkou, Zhaoyuan and Penglai, about 676.4 mm. The sunshine is decreasing from the eastern coast of the peninsula to the hilly and mountainous areas in the northwest, and it is 2834.43 hours in Dazeshan, Longkou and Penglai in the northwest. However, within an area of nearly 20,000 square kilometers, the peninsula is divided into several different communities. The mountains on the peninsula are undulating, mostly below 500 meters above sea level, mainly granite, and the highest peak is 1 130 meters above sea level. Crops can be harvested twice a year, mainly producing winter wheat, soybeans, corn and so on. Rich in pears, apples, grapes and other fruits. The coastline is tortuous, and there are many good deep-water ports, such as Qingdao.

Jiaodong Peninsula belongs to Jiaoliao Tailong, a quasi-platform of China and Korea. Archaean gneiss, schist and other deep metamorphic crystalline rocks are widely exposed, and there are extensive volcanic eruptions and acidic magma intrusions at the end of Cretaceous. After Miocene, Bohai Sea generally subsided to a great extent, becoming the largest Cenozoic faulted basin with the deepest subsidence zone in North China-Lower Liaohe River. At the end of Pliocene, especially since Quaternary, the Bohai Strait was fractured and subsided, and Shandong Peninsula was formed. The whole area is divided by two sets of faults, namely, NNE and NNW, forming fault blocks with different sizes. After long-term erosion and division, relatively broken low hills are formed. Several mountains stand out above the mountains. In the south of the peninsula, the elevation of the old peak of Laoshan Mountain is 1 133 meters, which is the highest peak in the peninsula. Yashan, Kunyu Mountain, Wade, Luoshan, Daze Mountain, Ai Shan, etc. In the north-central part, most of them are northeast. There are Taocun Graben Basin, Laiyang Fault Basin and Jiaolai Depression Plain among the mountains. There are strip plains with different widths along the coast, and the Peng (Lai) Huang (County) Ye (County) Plain has the largest area.

The coast of Jiaodong Peninsula twists and turns, and the gulf islands crisscross, which is a concentrated area of good ports along the coast of North China. Qingdao in Jiaozhou Bay, Yantai in Zhifu Bay, Weihai in Weihai Bay, Shidao and Longkou in Shidao Bay are all famous ports in China. The sand mouth beach on the peninsula is developed. Where sandbars are developed, islands are connected with land, forming land-connected islands, such as Zhifu Island near Yantai and Zhifu Island near Longkou. Except miaodao islands in the Bohai Strait, the coastal islands are all distributed in the coastal zone, and the larger ones are Elephant Island, Mo Xie Island, Dujia Island, Tian Heng Island, Liu Gongdao, Jiming Island, Kongtong Island, Chu Island, Sushan Island and Nanhuangdao.
