Find the location where my father took a photo in his youth. The challenge rated 1.5 🌟

A fan commented in the previous video that after his father was discharged from the military in 1992, he took a picture at a section of the Great Wall in Beijing. However, they no longer remember the exact spot and hoped I could pinpoint the location for them. They wished to revisit this place with their father and take another photo in the same spot.
Upon enlarging the photo, it's evident from the bricks and the distant landscape that this is indeed the Great Wall. Looking further into the distance, we see what's not connected to the main body of the wall-a beacon tower. As we know, the Great Wall was an ancient Chinese military defense system. Thus, the function of a beacon tower was to serve as an early warning and communication system. When enemies approached, smoke signals were used during the day and fire at night, with the volume of smoke or flame indicating the size of the enemy force. Typically, beacon towers are situated to the north of the wall's main structure. The place where his father sat is called an arrow window, which, as the name suggests, was used for attacking enemies. Therefore, the location his father was at must have been a watchtower. I noticed many people mistakenly refer to watchtowers as beacon towers, which is incorrect.

退伍在长城拍照未必是在北京或北京周边服役的兵。也有可能是路过北京的。

@@haochide6500 因为和你的立场不同，柴玲在境外势力帮助下妄图搞颜色革命，所以不能惯着，日本二战后从未认真反思战争罪行，所以国人愤怒。你不站在中国人的立场思考，肯定得不到正确答案。

纳闷，侦探很早就锁定北三楼了，为什么还花这么多时间，来确认细节？求证的时间远比解题的时间长太多。侦探太认真了。

推理出結果只是第一步，驗證結果的準確性一樣重要。不過，難度🌟評級只針對推理過程用到的範疇、知識、技能，不包含驗證的過程。其實驗證就是查資料而已。

IT專業的。只要生活中保持好奇心就行，多問為什麼，思考為什麼，查查為什麼。
