"You can go up to nine days to catch the moon, you can go down to five oceans to catch the dragonflies." Mao Zedong wrote romantic words in "Water Tone Song Tou · Resume Jinggangshan". The "Shenshi" return cabin that has traveled for nine days has long settled in Lushan, and the lunar soil samples recovered by Lushan No. 5 will also be preserved in Lushan in the future for disaster preparedness. These can be described as a deep consolation to Mao Zedong and other old proletarian revolutionaries, and the intersection of the space spirit and the red gene.
