Whether a person's five senses give people a cold feeling. The cold feeling combined with maturity often gives people a sense of visual aging. If the cold feeling is stronger, there will be a feeling of losing face and a certain sense of distance when getting along with people. At the same time, this appearance is also very recognizable. For example, some models can really be remembered at a glance.

Among the five senses, the most prominent cold feeling is the eyes. When judging, don't think that the single eyelid has a cold feeling. For example, Jinna in Rocket Girl 10 1 has double eyelids, but her eyes are cold, the inner corner of her eyes is sharp, and her eyes are long and narrow, which slightly covers her pupils, so the cold feeling in her eyes is also obvious.
