Short answers, pulled from the story.
Chang'e 6 was the first mission to retrieve samples from the far side of the Moon. Every previous sample-return mission, including China's own Chang'e 5, had collected material from the near side instead.
Chang'e 6 launched on the 3rd of May 2024 from Wenchang Space Launch Site on Hainan Island. Its return capsule landed by parachute in Inner Mongolia on the 25th of June 2024, after a mission lasting about 53 days.
Chang'e 6 landed in the southern part of the Apollo crater, inside the South Pole-Aitken basin on the lunar far side. Touchdown occurred at 22:23 UTC on the 1st of June 2024.
Chang'e 6 collected 1935.3 grams of lunar material using a robotic scoop and drill. The samples included surface soil, rock, and subsurface material gathered from as deep as two meters below ground.
Scientists hoped the samples might include lunar mantle material ejected by the impact that formed the South Pole-Aitken basin. Such material could reveal differences between the Moon's near and far sides and offer clues about the origin of the Moon and the Solar System.
Chang'e 6 was built and operated by the China National Space Administration as the sixth mission in the Chinese Lunar Exploration Program. It also carried instruments from French, Italian, Swedish, and Pakistani partners, plus a Chinese mini-rover named Jinchan.
