Put chestnuts on the sand, each layer is 3-6cm thick, and then lay a layer of wet sand, so that a layer of wet sand and a layer of chestnuts interact, or a layer of chestnuts and two parts of wet sand are stacked together. After stacking in layers or mixing, cover with 3~6cm sand, and then cover with dry straw. The chimney is about 1 meter high. This chestnut method can be stored after the new year.

(2) Choose a cool and ventilated room to store the bracts, or stack chestnuts and bracts in a well drained, cool open place. The reactor is 1-2 meters wide and no more than 1 meter high. Check the temperature and humidity regularly. If heaps of heat or dryness are found, water it to cool and add water. Cover the wooden pile with straw or sorghum straw to prevent freezing, and pre lay 10 cm of sand under the wooden pile. This method is kept until March to April of the next year, with good freshness and less decay, but chestnut sprouts more.

The fruit yield reached more than 95%.

(4) In the Tibetan drum method, put bamboo at the bottom of the washing and drying cylinder, put an air bamboo tube on the cylinder, pour chestnuts into the cylinder, lay a layer of chestnuts and pine needles, cover with pine needles, and connect seeds with bamboo.
