Detailed comments

(8) The weather is weathered, which is treated by clearing, treated by acid and warming, and supplemented by sweetness and bitterness.

"Weathering in the sky" is the four-day year of Jueyin Mufeng. "Qing wins, called the year of Jue Tian. This year should have been the first half of the year, and the climate is warmer, but it is actually dry and the climate is cooler. " The treatment is sour and warm, accompanied by sweetness and bitterness ",that is, although it is cloudy this year, due to the abnormal climate, it cannot be treated mechanically according to the atmosphere at that time, but according to the dry gas at that time. This is completely consistent with the above-mentioned treatment principle of "wind goes straight to the ground, clearing heat mainly, acid and temperature supplemented, bitter and sweet supplemented".

(9) The heat melts into the sky, and it is cold, and the sweet heat is bitter, that is, the year of Shaoyin Jun's fire. "Cold wins" refers to the year when there are fewer princes in Yin and fire is stronger than the sky. This year should have been the first half of the year with stronger heat and hotter climate, but it is actually colder and colder. "Treating heat with sweetness and suffering with bitterness", that is, although it is rainy this year, due to the abnormal climate, it is not possible to treat it mechanically according to the superiority of hot air, but according to the superiority of cold air.

(10) The sky is humidified, heat conquers it, and bitter acid cures bitter cold.

"Wet in the sky", that is, the year when the earth is too wet. "Hot wins" refers to a year when the toast is too wet. The climate in the first half of this year should be humid, with a lot of rainfall, but it is actually hot. "Treating bitter cold with bitter acid" means that although there are too many cloudy days this year, due to the abnormal climate, it cannot be treated mechanically according to the superiority of damp, but according to the superiority of hot air. What needs to be put forward is that it is meaningless to point out that "treating with bitter cold" and "helping with bitter acid", and treating with bitterness and helping with bitterness. According to the above, whenever the hot air can reach the sky, in the year of spring, or in the year when the hot air is overcome, it is treated with "salty cold" instead of bitter and dry products. So stealing is wrong, and it should be "treating salty cold with bitterness"

(1 1) When cremated in the sky, the cold will overcome it, and the sweet heat is the cure, and the bitterness is also accompanied.

"Cremation in the sky" is the year when the sun shines in the sky. "Cold wins" refers to a year when the sun is low. The climate this year should be warmer in the first half of the year, but it is actually getting colder and colder. "Take sweetness as approval and hardship as assistance", that is, although it is sunny this year, due to the abnormal climate, it cannot be treated as the superiority of internal heat mechanically, but as the superiority of coldness.

(12) Dryness melts into the sky, heat suppresses it, and bitter cold cures sweetness.

"Dryness turns to heaven", that is, the year of Yangming dryness in four days of gold. "Heat is better than sex" means the natural year of Yangming. This year's climate should have been dry gas prevailing in the first half of the year, and the climate was cooler, but it was actually hot gas prevailing and the climate was warmer. That is to say, although this year is Yangming's natural year, it should not be treated as dry gas mechanically, but as hot gas.

(13) Cold melts into the sky, and heat suppresses it, and salty cold cures it with bitterness.

"Cold weather" means a year when the sun is cold and the water is cold. "Heat beats it" means that in a sunny year, the climate in the first half of this year should be cold, but it is actually hot. "Treat cold and bitterness", that is, although this year is the sun's day, due to the abnormal climate, we can't treat it mechanically according to the superiority of cold, but according to the superiority of heat.
