Photography problem! Was this photo taken in the morning or at night? What lamp do you use? What color is the background?

The picture must have been taken during the day, so it is difficult to tell whether it is morning or afternoon. In short, it belongs to the mixed light of outdoor natural light and indoor soft light flashing umbrella. The wall is beige, or the white wall is adjusted with PS white balance or color temperature later. There are at least two soft light flashing umbrellas in the room. I agree with the previous netizen's judgment on the position of Zuo Qiang's weak flash umbrella.
