The characteristic of Guangdong's return to Nantian is that it always arrives on time, which is a familiar thing for southerners. Even if the clothes have been dried for a few days, the damp air on the floors and walls will still feel wet, which is a unique climate that is not found in the north, which makes people worry and worry.
This climatic phenomenon occurs in the southern coastal areas and heralds the onset of spring. As the cold air subsides, warm and moist airflows invade rapidly, causing the temperature to rise and the humidity to increase. As warm, moist air currents meet cold objects, they cause water droplets to form on the surface of the object.
Back to Nantian--- how to judge whether the tangerine peel is damp.
Check that tangerine peel should be kept in a dry environment and keep your hands dry. If you pinch the peel with your hands, you will find that the tangerine peel will not break and is malleable, which means that your tangerine peel is damp. 
The effect of Hui Nantian on tangerine peel is mainly the moisture in the air.
Therefore, it is key to prevent moisture intrusion, and close the doors and windows of tangerine peel storage to prevent outdoor warm and humid air from entering. If you find that the tangerine peel is too damp and the humidity reaches the level of softness, take it out to dry when the weather is fine.
There are several factors that are needed --- tangerine peel in the process of aging.
1. Effective contact with air.
2. Effective contact with sunlight.
3. Effective humidity control, so that it can be better aged, and the new skin can be well transformed, remember that it is too soft and easy to mildew, and it has been too hard to seal and suffocate, and it is the best conversion to open the lid properly to change the air. 
Because of the high sugar content and volatile oil of the low vintage tangerine peel, it is most likely to be mildewed and moth-eaten if it is damp for a long time. If you find mildew, if it is white hair, don't panic, sweep it off with a brush, and then dry it in the sun, if it has become green mold or black mold, choose to throw it away. 
If there is an insect moth, don't worry, just clean up the insect meal and insects and dry it again.
There is also a situation that will occur when storing new skins, burning skins.
What is Burnt Skin:
Burning skin refers to the phenomenon of black and deterioration of the epidermis or even carbonization, because the new skin contains more sugar, easy to absorb moisture, if it is stacked for a long time and not turned over in time, it will produce a rise in temperature and induce rapid glycolysis, resulting in the deterioration of the black skin, and even carbonization. The higher the degree of heat, the higher the sugar content, the more likely it is to burn the peel, so the chance of the big red peel will be greater.
