Well I think the photo's we saw from Q were taken around the time it was posted online. The first big clock time read around 6:40. Sunset in Chongqing is around 6:45 this time of year. The light looks like it was around sunset on a cloudy day. The next time is 7:00 which shows a dark sky so it's around this time of year. Not summer.
Also, the trees are covered in red lanterns. also red lanterns on the restaurant across the street from the hotel. This is to celebrate the Chinese new year holiday which has just happened over the last three weeks. The red lanterns are used just around the Chinese new year celebration. Also, everyone is wearing winter clothes.
I think the photos were taken the same day or around the day that they were posted by Q.
Also, the video you posted about the development of the hotel shows that there was a swimming pool in the location of the hotel up until 2007. When it jumps to 2009 they show the building of the hotel is underway. I'm not sure this has anything to do with Q though. Also, the hotel is a part of a larger building compound called Fuli Ocean Plaza. The hotel shows up on some of my maps as Fuli Ocean International. When I search that hotel I get results for the Hyatt Regency Chongqing. Not sure if it had a name change at one point.
I'm guessing Q is letting senior officials know that Q knows what was happening in the hotel or happening in Chongqing at the time the photos were taken. It was more of a message to say the things that were happening in secret are not secret and Q has people on it. Maybe there was a meeting at the hotel or maybe there was some even in Chongqing or meeting in Chongqing and persons of interest were staying at the hotel. I think its more about Q letting them know that Q knows.
Also on Jan 11th Q posted that a VIP senior official was arriving in China and asked which senior official would be arriving and why. Maybe it is connected. Maybe not.
I'm new to posting here. not sure the best place to post. Is there another place I should be posting or another discussion I could be looking at?
