Not only did filming in the mountains present a food supply problem, the wide fluctuation of nighttime and daytime temperatures often caused the electric motors and batteries the cameras had to use to malfunction. Sometimes someone would be sent on a special trip down the mountain with equipment for maintenance or repair. A round trip took more than four days at a minimum and was quite enervating.
在高山拍攝不但補給困難，更由於高山早晚溫差大，攝影機必用的發電機和電瓶經常故障，有時專程派人揹下山維修或更新，來回的路程至少 4 天以上，相當辛苦。
