During a recent work trip to Beijing in early December, we did a short walk at part of Great Wall of China. My face, hands and feet were freezing cold when it was windy, even though I was wearing a thick beanie, down jacket, thermal layer, socks and gloves. I felt like an old lady as I slowly climbed up and down the flights of steps at the less challenging stretch of the Great Wall. It was a nice experience to share with my other 3 colleagues being my first time there. I'm not sure when I will next visit it again.
