My comments :  This is another fantastic achievement by China.  They have got it right the first time without any hitches. Previous to this China landed their first moon rover on the moon. This Chang-e 4 is no different.  The 'difficult' hurdle of no communications (because it is on the dark side of the moon) was solved by parking a communications satellite off the moon's dark side to relay radio signals back to earth. Here is a quick YouTube from sometime before Chang-e 4 :
