After graduating from college, I bought some melatonin and Hongmao medicinal liquor for the elderly at home. For those who love drinking, you can drink some Hongmao medicinal liquor during the process of abstinence. After all, Hongmao medicinal liquor can improve the immunity of the elderly, and can also give up drinking, but you can't eat more health care products. The best way is to improve physical fitness through food supplement.
