1, the wisdom of the ancients (Taoism is natural): wooden barrels, wood, born out of the ground, traveling eastward; Like its roots. The natural combination of wood and nature began with protecting roots and feet, which was the first choice for ancient people to soak their feet, rather than bronze and other utensils at that time; In addition, today's research found that the ancients especially liked to soak their feet for health. Traditional Chinese medicine is in contact with iron, aluminum, copper and plastic in hot water, which is easy to produce tannic acid reaction and produce harmful substances. Therefore, soaking feet in wooden barrels should prove the wisdom of the ancients.

2. Harmony of Yin and Yang: wood, the five elements should be in spring, and everything grows and belongs to Yang; Generally, soaking feet at night should be related to the winter in the four seasons, and everything is cloudy. Generally speaking, the feet are soaked in hot water at night, and the wooden barrel keeps warm and does not conduct heat, so the feet are warm and comfortable to put in. Nowadays, people use plastic or stainless steel utensils. Although the water is hot, the bottom of the basin contacted by the feet is really cold after putting them in the feet. Can you be comfortable and can you exercise?

3. What about wooden barrels and pots? Is there a foot bath bucket instead of a foot bath tub in ancient and modern times? It is known that the viscera of the human body correspond to the meridians of the soles of the feet. The ancients found that soaking feet with four fingers below the painted joints had the best health care effect, so they made a foot soaking bucket, which can only be called washbasin and footbath.
