Hetian jade has been rubbed by hand for several minutes. Is there a relationship between oil yield and weather temperature?

There is no such thing. Mainly depends on what kind of material, such as all-white meat seed material. There is also leather pigment, which is relatively difficult to separate oil. For meat, it is also oily. It must be the fineness of the material, that is, the high density is good. It is easier to serve food in hot weather than in cold weather. Because the human body excretes a lot of oil and sweat, it is better to eat vegetables.
