Jiangshan Ruler

Lin Chen, a doctor of modern geography, was a poor scholar in the Jianyan period of the Southern Song Dynasty. He had a jade sign in his mind that could "see" mountains and rivers - Jiangshan Ruler. What others see is fame, but what he sees is space. Quanzhou, the place of "distribution" in the eyes of people at the time, was exactly the starting point of the Maritime Silk Road that he had studied for two years. Instead of going north to regain the Central Plains, he used geography to leverage the turn of a continental civilization: he used hinterland theory to revitalize seaports, he used typhoon structure to reverse into the eye of the storm to save the lives of a full ship, he used political geography to walk the tightrope between Yue Fei and Qin Hui, and he used economic geography to weave a huge trade network across the Indian Ocean. This is a hard-core knowledge article with a refreshing feel - every slap in the face relies on real knowledge, and every victory has real historical weight. It is also a thick historical novel - Yue Fei's death, the Shaoxing peace talks, and the dispute between the ocean and the Central Plains are all reopened on the premise of respecting historical facts. It is also an enlightening book of modern consciousness - scientific methods, quantitative thinking, marine civilization, systems are greater than people's rule, borrowing things without excuses, quietly changing a person, a city, and a civilization's understanding of the world. From a sea map of Quanzhou to the last stroke of the world map, Lin Chen wants to answer: Can a nation accustomed to looking north turn around and face the sea.
