English: When it comes to the challenge of Extreme weather, sorry, I haven't experienced too many. My hometown's weather is usually moderate and suitable to mankind's life. Other places I travelled or used to live were also alright. If you still would like me to point out one, from subjective impression, I would say: 2015 trip to Tibet with the Altitude sickness (Wikipedia introduction: https://en.wikipedia.org/wiki/Altitude_sickness) was really hard from its extreme weather of lower oxygen, lower air-pressure, much colder and higher height. Like in this picture, our height was shouldering with Jade Dragon Snow Mountain (Wikipedia introduction:https://en.wikipedia.org/wiki/Jade_Dragon_Snow_Mountain ), which made my appreciation of beautiful landscapes harder than before. But now, in reviewing it, my sense is: WoW, so beautiful and worthful!
