This aerial photo taken on Nov. 15, 2023 shows the Simatai section of Gubeikou Great Wall in Beijing, capital of China. Gubeikou Great Wall is located in Gubeikou Town, Miyun District of Beijing. The defense of the Great Wall is an important part of the early Chinese People's War of Resistance Against Japanese Aggression. In 1933, the Chinese troops fought against Japanese invaders at places including Lengkou, Xifengkou and Gubeikou of the Great Wall.

As a part of the national anthem lyrics, the Great Wall is the spiritual symbol of the Chinese nation. The ancient Great Wall has witnessed Chinese people's patriotism, solidarity and strength. (Xinhua/Chen Zhonghao)
