Chen Shengzhi was a minister during the Northern Song Dynasty, the prime minister during the Reign of Emperor Shenzong of the Song Dynasty, and one of the figures of the "Four Phases of the Flower Feast".

Chen Shengzhi's old strategist was very calculating, and Wang Anshi was appointed as the prime minister, worried about talking about the manchu court, and introduced Chen Shengzhi to assist him. Chen Shengzhi knew in his heart that he was incompetent, but he tried his best to be used by Wang Anshi, and Wang Anshi, in order to be grateful to him, let him be the prime minister before himself. He understood that the "Wang Anshi Transformation Law" would definitely fail, and as soon as it was reused, he requested the dismissal of the Regulations Department, and from time to time there were some small differences, which on the surface seemed to contradict Wang Anshi. The world ridiculed him for this, calling him "The Mirror."
During the reign of Emperor Shenzong of the Song Dynasty, the Goryeo Kingdom sent people to the Northern Song Dynasty to pay tribute, and the envoys asked for local maps from the prefectures and counties they passed, and these places must be given, ready-made for ready-made, temporary drawings without ready-made, mountains and rivers, roads, topography, and dangerous passes, all of which must be clearly and clearly drawn.
Why do I have to give? Because this was approved by the imperial court, the imperial court also issued official documents.
The map has always been very strictly managed, because it belongs to a state secret, and the Court of the Great Song Dynasty actually sent it to a foreign country and a Fan country, and took the initiative to "sell" state secrets, which is really puzzling, and can only show that the imperial court has no sense of national security at all!
When the Goryeo envoys arrived in Yangzhou, they still took out official documents and asked the Yangzhou officials for a map. At that time, Chen Shengzhi was appointed as the envoy of the Zhenjiang Army and stationed in Yangzhou. He said to the Envoy of Koryo, "Please show me the map you received earlier, and I will draw it accordingly." The Goryeo envoy did not know what the plan was, and when he brought all the maps he had received before, Chen Xiugong burned all the fire and reported the situation to the imperial court.
In the early years of the Northern Song Dynasty, Zhao Kuangyin, the grandfather of the Song Dynasty, sent Lu Duoxun as an envoy to the Southern Tang. When the ship stopped at Xuanhua Pass when the Southern Tang returned, Lu Duoxun sent someone to say to Li Yu, the lord of the Southern Tang Dynasty, "I am going to rebuild the map of the world." At present, our National History Museum only lacks maps of your jiangdong states, and I would like to take back a map of your states this time. Li Yu quickly sent someone to transcribe and copy it and gave it to him. In this way, Lu Doxun clarified the geographical situation of the Nineteen Prefectures of southern Tang, the defensive fortresses, and the number of tiger mouths. Since then, the Song Dynasty has begun to have the intention of fighting against the Southern Tang. Chen Shengzhi's move was precisely because he was vigilant about the past events.
