假如你现在在长城游玩,请给你父母写张明信片,说说你此刻在做什么（英文的）

Dear mom and dad,I'm now visiting our marvelous Great Wall and everything that catches my eyes is so amazing! ''He who has never been to the Great Wall is not a true man".See ? I'm a 'true man' now ! Hope this card finds you well. --xxx
明信片上由于空间限制不可能写太多,以上就行了. :)
