Because this requires a quantitative index, cashmere sweaters are theoretically warmer than sweaters, but cashmere sweaters are also warm and not warm, which is also related to the cashmere content of cashmere sweaters, and sweaters are the same.

How to keep warm

? (1) Keep your head warm. Medical research has found that when the ambient temperature is 15℃, the heat lost from the head accounts for 30% of the whole body heat, and the heat lost at 4℃ accounts for 60% of the whole body heat. In addition, the cold weather makes blood vessels contract, and people will have headaches and dizziness. For people with cerebrovascular diseases, it is easy to induce cerebrovascular diseases.

? (2) Keep the chest and abdomen warm. People often say that wearing a scarf in winter is like wearing an extra dress. After catching cold in the chest and abdomen, it is easy to break the body's yang and lead to a heart attack. In addition, it can also induce gastrointestinal diseases, so keeping warm in the chest and abdomen is also a link that cannot be ignored.

Matters needing attention in online shopping

? (1) Identify merchants: Personally, I think it is best to buy on the B2C platform instead of the C2C platform. It is best to buy in some big online shopping malls, such as Taobao Mall, Baidu Youah, JD.COM Mall, Tencent Paipai, Yi Bei, Dangdang and so on.

? (2) Don't be greedy for cheap: Many people shop online to get cheap. If the goods in the online mall are cheaper than those in the market 10% to 20%, I personally suggest that you can boldly pay the bill and deliver it to your door after he pays the bill.
