We'll start from the General's Tower and head east toward Jingshanling. In 1933, the Chinese army fought against Japanese invasion troops in Gubeikou. In the four-month-long battles, over 5,000 Japanese soldiers died, while 9,000 Chinese soldiers sacrificed their lives. It was terrific that the ancient Wall is not merely a relic but remained a battlefield in the modern world. The General's Tower was the headquarters of the Chinese defense force.
We'll finally reach the 24-eyed Tower. It was the last enemy building on the Great Wall's eastern side, echoing the famous General's Tower during the war. It has three upper and lower floors, three arrow windows around the first two floors, and battlements around the top floor. The 24-eye building with 24 viewing holes is a rare treasure in the history of Great Wall architecture. Despite only one wall left, the tower is spectacular, a bit like the ancient Roman Coliseum! The twenty-four-eye building is also the end of the Great Wall section of the Gubeikou, from where we'll make a U-turn back to the General's Tower to end today's adventure.
