Socially Distanced Santa

Christa Larwood finds out how trips to see Santa are changing as we prepare to celebrate Christmas in a pandemic; We head to Mount Everest, now closed to climbers, to find out how its famous sherpas are coping with the loss of work; Amanda Ruggeri's in China to look at some of the high-tech solutions to fix crumbling sections of the Great Wall; and we catch up with the couples separated by closed borders, but hoping to be reunited for Christmas.
