Investigating Triangular Shaped UFO Spotted in Shanghai, China r/UFOs

Just to preface, I'm not saying this isn't a shadow at all, so don't jump down my throat here: am i watching a different video then you guys? This guy did a great job and took a lot of time to do this I'm sure, but at the end of the day the big "gotcha" moment was a bar owner showing him a picture on his phone of a completely different shadow from a completely different building taken a year before....from reading your guys comments i expected something way more then that by the end. Hell there were photos floating around on here that do a far better job of debunking this then guy holding up a picture of something completely different on his phone.

It is probably a shadow, but these buildings have literal spotlights drilled into the sides of them: you should see this same shadow every cloudy day and be able to find that building easy.

Also the shadow in the sky is clearly a triangle. Not two sides of a triangle (aka 2 sides of a square building like in this video). I'm not saying it's wrong, again, but it isn't some crazy debunk video at all. Please someone go film the sky on a cloudy day, you should immediately see this shadow and we can move on, it will always be in that exact same spot.
