The giant pandas Xing Ya and Wu Wen have not paired despite all the efforts of their caretakers. The period in which this should be possible has passed, so it will now take another year before it can happen again. But then Wu Wen still has one last revival. Barbary Macaque Viktor has been found in a city plantation, with a diaper and collar on. He has probably never been in contact with peers. He needs to learn how to act like a barbary macaque. Otherwise, the group, especially alpha male Kees, will forcefully let him know that he is not welcome.
