I am a person who would frighten easily. When I noticed that travelers who would like to visit the Everest Base Camp or/and Mount Qomolangma would have altitude sickness. At that moment, I am hesitating whether or not I should join because I am afraid that my health would not allow me to do so.
However, I have overcome my worries and chose to go at last and I did not regret my choice because the sceneries and local people I met there have totally changed my mind towards this deep and unmeasurable world. You could feel their happiness by the big and friendly smile shown on their face, which you could rarely found in our busy and rapid Hong Kong.
