In autumn and winter, the temperature is low and the air is dry, so Wan Wen, which is used for collection, also needs special care. First of all, we should pay attention to moisture-proof ventilation to avoid mildew, deformation and rust in Wan Wen. Secondly, attention should be paid to avoid direct exposure to high temperature and strong light, so as to avoid some Wan Wen losing its color due to thermal deformation or excessive exposure to light and illumination. In addition, we should also pay attention to the interval storage between Wan Wen, which can be isolated with some buffer materials to avoid collision damage. Finally, some professional cleaning and maintenance can be carried out in time, such as wiping and waxing, so that Wan Wen can maintain a good appearance and quality.
