The human body and the natural environment are actually corresponding, as follows:
The sky has the sun and moon, and people have their eyes;
The heavens have five elements, and humans have five internal organs;
There are six Qi in heaven (cold, hot, warm, hot, dry, and humid), and six meridians in humans (Sun, Yangming, Shaoyang, Taiyin, Shaoyin, and Jueyin);
The sky has four seasons, and people have limbs;
There are 360 days in a year, 360 points for people, and 360 sections for the human Skeleton;
There are twelve months in the sky, twelve major festivals in human bones, and twelve orifices in humans, following the flow of the twelve hour meridians;
There are seven days a week, and people have seven orifices on their heads;
Heaven and earth have meridians and latitudes, while humans have meridians and collaterals;
There is a meridian and equator in heaven and earth, while in humans, there is the Xiaozhoutian (Ren Du Er Mai) and Dai Mai;
The land has rivers and mountains, and people have blood, muscles, bones, and so on.
Man is actually a microcosm of heaven and earth. A drop of water knows the sea, a leaf falls and knows autumn, and a person knows all things in the universe.
人体和自然环境其实是相对应的，具体如下：
天有日月，人有双眼；
天有五行，人有五脏；
天有六气（寒热温暑燥湿），人有六经（太阳、阳明、少阳，太阴、少阴、厥阴）；
天有四季，人有四肢；
一年有360天，人有360穴，人体骨骼系统有360节；
天有十二个月，人骨有十二大节，人有十二窍，遵循十二时辰子午流注运行；
天有每周七天，人有头部七窍；
天地有经纬线，人则有经络；
天地有子午线、赤道，人则有小周天（任督二脉）、带脉；
地有江河山脉，人有血液、肌肉、骨骼等等。
人其实是天地的缩影，一滴水而知大海，一叶落而知秋，一个人而知宇宙万物。
