Chinese medicine practitioners who used to be barefoot thought that "spleen belongs to soil", so the best place to walk barefoot is soft and flat yellow land or grassland. It should be noted that it is not advisable to walk barefoot in hot weather to avoid scalding the soles of your feet. After autumn, the temperature began to drop gradually, the summer heat gradually disappeared, and the cold was not felt. You can use this time to walk more, and it is in line with the principle of "nourishing yin in autumn and winter". If you have no conditions to go barefoot, you can also wear cloth shoes to walk on land.
