• The Five Elements "Wood, Fire, Earth, Metal, Water" are tangible, while the Six Climates "Wind, Cold, Heat, Dampness, Dryness, Fire" are intangible. As stated in the "Book of Changes": "In heaven, they form images; on earth, they take shape, and thus changes and transformations are visible. " The numbers 1 to 4 of the River Chart represent the intangible in heaven, which interacts with the number 5 of the earth to produce the numbers 6 to 9, representing the tangible on the ground. The concept in the "Inner Canon" that the Six Climates in heaven produce the Five Elements on earth is entirely correct, contrary to the book's claim that "it doesn't hold up in reality." In fact, it is the book's confusion of the Five Elements and Six Climates that "doesn't hold up."
  
• The book suggests that "the sun's light and heat hide in the water under the soil and ground in autumn and winter, and rise to the surface in spring and summer," and also claims that it is "atmospheric pressure" that forces the summer heat underground in autumn. However, in reality:
  1. The deeper underground, the hotter it gets, and the less related it is to the surface temperature. For example, for every 50 to 100 meters deeper into a mine, the temperature rises by about 1°C; for every kilometer deeper underground, the temperature increases by about 20 to 30°C, because the earth's core contains magma in a high-temperature state, and the earth itself continuously emits heat from the core outward.
  2. 
     The annual variation in soil surface temperature Soil is not a good conductor of heat, and the rate of heat conduction is very slow. Throughout the year, the surface temperature reaches its highest around July and August, while the highest temperature a few meters below the surface occurs around September and October; the surface temperature is lowest around January and February, while the lowest temperature below the surface occurs around March and April. Moreover, the temperature underground generally does not change much. If the surface temperature varies by -20 to 25°C over the seasons, the temperature 5 meters underground only changes by 3 to 5°C. The reason why well water feels warm and mines feel warm in winter, and well water feels cool and mines feel cold in summer, is because the surface temperature changes significantly with the seasons, while underground, it lags behind. In summer, when the surface is hot, the temperature underground <地表的，故人感覺井水涼、礦坑冷；冬天地表冷，地下的溫度> is lower than the surface, so people feel the well water is warm and the mines are warm. It is not, as the book suggests, that in winter, the heat from the surface hides in the underground water, making the well water warm.
  3. The flow of heat is independent of atmospheric pressure and is related to the temperature difference. Heat flows from high temperature to low temperature, and the greater the temperature difference, the faster the flow rate. During the year, around September to October, when the surface temperature begins to be lower than the underground temperature, the underground heat will emerge to the surface, without waiting for the next spring. The temperature difference between the underground and the surface reaches its maximum in December and January (around the winter solstice), and the heat emerging from the underground to the surface also reaches its peak; the temperature difference between the surface and the underground reaches its highest in June and July (around the summer solstice), and the heat penetrating from the surface into the underground also reaches its maximum. In other words, in spring and summer, heat penetrates into the ground; in autumn and winter, heat emerges from the ground, which is exactly opposite to what is stated in this book: "The heat descending into the ground from the beginning of autumn reaches its maximum at the winter solstice; the heat rising from the ground from the beginning of spring reaches its maximum at the summer solstice."

• This book fails to correctly understand "Sovereign Fire" and "Ministerial Fire." "Sovereign Fire" refers to the light and heat of the sun; "Ministerial Fire" refers to "geothermal heat," "heat stored in water," and the energy and heat produced by the broad sense of "combustion" (i.e., oxidation) of all things. All life phenomena and climate changes on the earth's surface are mainly driven by the light and heat of the sun, just as the human body has a heart. However, the sun's light and heat intermittently shine on the earth's surface. During the night without sunlight, the generation and preservation of temperature are temporarily supported by "Ministerial Fire." "Ministerial Fire" is closely related to water. The heat produced by the sun during the day and the combustion (oxidation) of "Ministerial Fire" is mainly preserved by water, because among the common substances in the earth's crust, water has the highest specific heat (1cal/g‧℃), and the amount of water is also relatively large, which can best maintain the thermal energy of the earth's surface, so that the temperature difference between day and night is not too large, just as the human body has oxidative combustion and a large amount of water to maintain body temperature. In dry deserts without water (the specific heat of dry sand is about 0.19cal/g‧℃), even if it is extremely hot during the day, the night is extremely cold, and the temperature difference between day and night is often more than tens of ℃. "Ministerial" assists "Sovereign," "light and heat" belong to "Sovereign Fire," "fire and heat" belong to "Ministerial Fire," the existence of "Ministerial Fire" is to assist the inadequacy of "Sovereign Fire," which is the reason why the ancients named it.

Shen Yaozi said, "The sun bakes the earth, dissipating all things."
