There are four main differences. The first is aversion to cold. I don't hate cold because of wind and heat, but I'm a little afraid of wind. Fear of cold is very heavy. The so-called aversion to cold, that is, wearing a lot of clothes or covering the quilt, or heating yourself there, can not alleviate the feeling of cold. This is called aversion to cold, and aversion to cold is very heavy. The second is runny nose. The characteristic of wind-cold cold is runny nose like clear water, which can't be controlled. Some patients use a roll of toilet paper for half a day. The characteristic of wind-heat cold is nasal congestion, which is thick and yellow, and there is no clear water-like nasal congestion. The third is a sore throat. A cold has no sore throat, and the throat can itch, but it doesn't hurt; Wind-heat cold has obvious sore throat and weak throat, which is the feeling of wind-heat evil. Wind-heat evil can easily invade the throat and mix into the lungs when it goes up and down. Therefore, wind-heat cold has obvious characteristics of sore throat. Fourth, the tongue and pulse are impassable. The characteristics of wind-cold cold are white tongue coating and tight pulse; Wind-heat cold is characterized by yellow or greasy tongue coating and rapid pulse. So we can distinguish wind-cold from wind-heat cold from aversion to cold, sore throat, runny nose and tongue pulse.
