The distant stars, the bright river and Han. Looking up, the visible sun, moon, and stars nourish humanity's initial curiosity and faith. As a record of observing stars and measuring the sky, the history of star charts can be traced back more than 10000 years ago. During the Ming and Qing dynasties, scientists systematically introduced the latest astronomical achievements from Europe, achieving a new situation of star mapping that was both domestic and foreign, and inclusive. The "Equatorial North South Star Map", which was completed nearly four centuries ago, is a prominent representative of this. Recently, the archive cultural relics exhibition of "The Great Road goes hand in hand with the sea and embraces all rivers - from the historical echo of the 'Silk Road' to the practice of the 'the Belt and Road' in Shanghai", which ended, displayed a copy of the "General Star Map of the Equator in the North and South". A continuous stream of viewers stood in front of the star map, stopping to admire, as if walking into a time tunnel, and memories of cultural exchange in the starry sky came towards them. The Harmony of Eastern and Western Celestial Literature Traditions: The North and South General Star Map of the Equator is the earliest and largest surviving imperial star map of the East, created in 1634 by the late Ming scientist Xu Guangqi. It was jointly produced by scholars from the Imperial Academy and foreign missionaries such as Tang Ruowang and Luo Yagu. The Qingneifu edition (hereinafter referred to as the "Yiduan edition"), which is stored in the First Historical Archives of China, is a screen mounted wooden printed and colored paper edition. The entire picture is divided into 8 vertical sections, with a horizontal length of 449.6 centimeters and a vertical length of 202 centimeters. The main body of the star map is the North and South Equatorial Star Map, with a blue sky and golden dots on the celestial bodies. Each hemisphere map has a diameter of about 160 centimeters, starting from the vernal equinox point. The traditional Chinese equatorial and European ecliptic coordinate systems coexist. In terms of constellation identification, the traditional Chinese star official naming and classification system of "Three Enclosures and Twenty Eight Constellations" is adopted, with reference to Western star catalogs and measured data for correction. "San Yuan" refers to three areas in the sky surrounded by stars, resembling three cities. The area centered on the northern celestial pole is called "Zi Wei Yuan", while the other two are "Tai Wei Yuan" and "Tian Shi Yuan". In the star chart, the Purple Micro Wall is the Forbidden City in the starry sky, while the Heavenly Market Wall is a marketplace for the common people, with regional names such as Wuyue and Bashu serving as the market walls... All things in the world reflect on the starry sky, with a unique Eastern charm. For Antarctic stars that are not recorded in the old map or cannot be observed within China, they will be added to the star map after translation based on Chinese customs. For example, "Immortal Bird" is translated as "Firebird", "Big billed Bird" is called "Bird's beak", and "Paradise Bird" is named "Yique". In this way, the surveyors increased the number of traditional Chinese star maps from 1461 to 1812, and introduced the concept of "magnitude" to distinguish all stars into sixth order, marked by dots of varying sizes according to the legend. In addition, the Milky Way, which runs through the north-south star map and looks like a white line, is marked with dense dots for the unnamed stars. According to telescope observations, the traditionally considered non stellar "gas" is clearly defined as a group of stars, which is what we call a nebula today. Between and along the northern and southern equatorial star maps, there are 16 auxiliary maps, including ancient equatorial star maps, ecliptic star maps, and Western astronomical instrument maps, accompanied by corresponding explanatory notes. At the beginning and end of the entire image, there are Xu Guangqi's signature "Explanation of the Two General Star Maps of the Equator North and South" and Tang Ruowang's "Explanation of the Two General Star Maps of the Equator North and South", which explain the reasons for the mapping, the mapping rules, and the technical path of harmonizing the traditional astronomy of the East and the West
