Far-side landing required a precursor relay satellite: Queqiao, launched six months earlier, parked in a halo orbit around the Earth-Moon L2 Lagrange point. Chang'e 4 then used a translunar trajectory, lunar orbit insertion, and a near-vertical powered descent into Von Kármán crater, the first soft landing on the lunar far side, and Yutu-2 is still rolling.
