China is an ancient civilization with a long history and great changes. Although our country has a long history, everyone has an unforgettable experience in his heart. The destruction of opium in War of Resistance against Japanese Aggression and Humen, the September 18th Incident and the July 7th Incident are all vivid. But the history of our country also has a bright side.

It was the ancients who invented Chinese characters. Long ago, the ancients could not write or take notes. Someone figured out a way to tie a knot, but it was too much trouble. A man named Cang Xie invented Oracle Bone Inscriptions.

Those poets and writers are indispensable in the cultural history of our country. Wen Tianxiang's "Crossing the Zero Ding Yang" is an eternal quatrain; Meng Jiao's Ode to a Wanderer praised the great mother. Li Bai's Thoughts on a Quiet Night expresses his homesickness. And those famous writers. Sima Qian's "Historical Records" was called by Lu Xun as "a masterpiece of historians, and Li Sao has no rhyme"; Sun Wu's The Art of War is a treasure in the classical cultural heritage. Confucius' Book of Rites is an important book of laws and regulations in ancient China.

Our country also has beautiful rivers and mountains. The Great Wall is the pride of ancient China people. It is 6330 kilometers long and can be seen clearly with the naked eye in space. Mount Everest is as high as 8444.43 kilometers; Namco is the highest saltwater lake in the world, with an altitude of 4718m. The Yarlung Zangbo Grand Canyon is the largest canyon in the world, with a depth of 6009 meters. ......
