Characteristics of soil: "Soil is beneficial to crops". "Harvest" refers to the sowing and harvesting of crops, that is, the so-called "spring planting and autumn harvest". Soil has the function of sowing crops, harvesting grains and growing everything. Furthermore, the soil has the characteristics of growth, bearing capacity, metaplasia and long-term cultivation. All things and phenomena that have the functions of growth, fruiting and metaplasia can be attributed to soil.
Characteristics of gold: "Gold is said to go with leather". "From the skin" has two meanings: obedience and change. "Obedience" is the embodiment of Jin's "strong" character, and "change" is the embodiment of Jin's "softness". At present, what is usually called "skin-peeling" means that gold has the characteristics of cold, astringent, latent and clean. The weapon cast by gold is hard and sharp, but the shape of the weapon can be changed according to people's wishes, so gold also has its "soft" characteristics.
