I would like to ask, why not take Xiajin County, Shandong Province when planning the railway? Please reply if you know, thank you.

Xiajin has never planned a railway in this place. Who did you hear that Xiajin planned the railway? It never happened. Not in the Republic of China, nor in New China. At present, the latest national long-term railway planning and the four vertical and four horizontal railway network planning in Shandong Province have nothing to do with Xiajin.

The railway across the plain is beijing-shanghai railway, which was built in the Qing Dynasty. At that time, it was from Texas to Jinan, and Xiajin was never considered. It is estimated that the foreign engineers who designed the line at that time didn't know that there was a Xiajin in China.
