China launches Chang'e-5 mission to collect moon samples, the first of its kind in the world for over 40 years. A part of the 2kg of samples will be buried in Mao Zedong's home province Hunan, in memory of Mao using a moon mission analogy to express revolutionary romanticism in a poem: We can clasp the moon above the Ninth Heaven and seize turtles deep down in the Five Seas. We'll return amid triumphant song and laughter. | Xu Zeyu
