Why do I look different in the mirror of the hotel, home and barber shop? The ugly barber shop is real.

First, the mirrors in hotels, homes and barbershops are different (looking at the full-length mirror will ignore the whole, and the barber's half-length mirror will focus on the head and will involuntarily enlarge the shortcomings of the head)

Second, the lights in hotels, homes and barbershops are different (why is everyone's skin so white and beautiful under the lights of some concerts? Apart from makeup, it is difficult for people's skin to be white in that light. Just like the skin taken under the condition of backlight and backlight when taking a selfie is completely different, you can try it)

Third, the mood in the hotel, home and barber shop is different (upstairs).
