　　Hang a year to 2 times a year, one to two months. The rest of the time should be collected. Tibetan environment to strict requirements.

Control humidity, mainly using desiccant color silica gel or anhydrous calcium chloride. Control temperature, air conditioning can be used to adjust the indoor temperature.
