TR3B over Fujian, China on 31 January 2025?

[Starflint]

This is a video sent to me by a netizen, with detailed DTL，However, the video is currently only available as an edited version.

D：31 January 2025
T： 5:51PM CTZ
L：Ningde, Fujian Province, China
Flight Information：XiamenAir 8548 【CXA8548/ MF8548】

My first thought was that it was just a reflection or artificial light from something on the ground：

I found ADSBex at the time，The plane was only 14,400 feet above the ground:

Then there's the comparison in googlemap:
Lianjiang County, Fuzhou City, Fujian Province, China

Through the direction of the plane, as well as the relative motion of the object and the clouds disappearing backwards in the video, I speculated that the photographer was shooting from the right side window of the aircraft, that is, the west, so I looked for a more suitable area in the map, but it is still difficult for me to figure out where the equilateral triangle and three points of light are caused? Could they be street lights or square spotlights？

There may be spotlights in the square

or maybe my thinking and looking for the location is not accurate, which is not my strong point...

My first thought is that it is a reflection of something behind the camera, or even possibly a reflection of highlights/lights on the camera itself seen reflected in the plane window.

Could they be street lights or square spotlights？

My first impression was that it looked like something attached to the ground, with an illusion of motion because there's a car moving to the left
