An instinct makes men read 100 years old from the age of 20, and often read books of health and wisdom that are often rewarding. Liver and kidney are the source of male masculinity. When a man raises his liver and kidney, he is full of vitality. Starting with the two systems of "liver and kidney" in TCM, this book systematically and comprehensively expounds the decisive role of liver and kidney in men's physical and mental health. At the same time, combined with the lifestyle and eating habits of urban men in today's society, simple and easy methods such as diet therapy and meridian health preservation are adopted to help human yang, solve diseases caused by liver and kidney weakness, kidney deficiency and sub-health, and help men's "fire of life" to stimulate innate vitality! I believe that the publication of this book will definitely give guidance to men's health and wellness.
