The Waterborne Observatory developed by Su Song is a giant astronomical instrument, with a height of12m and a width of 7m, just like a three-story building.

2. In the early years of Jiayou, Su Song was ordered to revise and compile medical books. In the second year of Jiayou (1057), he and Zhang Yuxi, Lin Bu, etc. jointly compiled Supplementary Notes on Jiayou Shennong's Materia Medica (referred to as Jiayou Materia Medica).

3. Su Song has drawn more than 50 complete drawings, sub-drawings and parts drawings about astronomical instruments and mechanical transmission in The Essentials of New Images, and drawn 150 kinds of mechanical parts, most of which are perspective views and schematic diagrams. This is the earliest and most complete mechanical drawing preserved in China and even in the world. It is based on these drawings that Mr. Wang Zhenduo, Mr. Needham and others can accurately restore the whole picture of the water transport instrument.

4. Su Song has also drawn many kinds of star maps with new instruments and image methods, such as the Star Map of Hunxiang Ziwei Yuan, the Star Map of Hunxiang Northeast and Foreign Officials, the Star Map of Hunxiang Southwest and Foreign Officials, the Star Map of Hunxiang North, the Star Map of Hunxiang invivo, the Star Map of Four Seasons and Midheaven, and the Star Map of the Spring Equinox.

5. After Su Song and Han Gonglian completed the platform of water transport instrument, they independently developed the hydrodynamic muddy sky. People drill into the celestial sphere to watch, and drill holes in the celestial sphere into stars, which is very realistic. This is the first clearly recorded false celestial phenomenon in the history of our country, and its creativity is unprecedented.
