On the sixth day of junior high school, we reversed early in the morning and went straight to the Thirteen Tombs. We visited the Dingling Tomb and went down to the underground to see the Tomb of Emperor Wanli in the Ming Dynasty. In the afternoon, I climbed the Great Wall of Juyongguan, which is the most powerful Pass in the world. I went up to the eighth enemy building and was half dead. I can imagine the hardship of building that year. The bus ride was too long that day, and basically spanned the city of Beijing.
