春三月∶尸经两三日，口、鼻、肚皮、两胁、胸前肉色微青；经十日，则鼻、耳内有恶
汁流出， (匹缝切，胀臭也)胀；肥人如此，久患瘦劣人，半月后方有此证。
夏三月∶尸经一两日，先从面上、肚皮、两胁、胸前肉色变动；经三日，口鼻内汁流、
蛆出，遍身 胀，口唇翻，皮肤脱烂， 胗起；经四、五日，发落。
暑月罨尸，损处浮皮多白，不损处却青黑，不见的实痕。设若避臭秽，据见在检过，往
往误事。稍或疑处，浮皮须令剥去，如有伤损，底下血 分明。
更有暑月九窍内未有蛆虫，却于太阳穴、发际内、两胁、腹内先有蛆出，必此处有损。
秋三月∶尸经二、三日，亦先从面上、肚皮、两胁、胸前肉色变动；经四、五日，口鼻
内汁流、蛆出，遍身 胀，口唇翻， 胗起；经六、七日，发落。
冬三月∶尸经四、五日，身体肉色黄紧，微变；经半月以后，先从面上、口、鼻、两胁
、胸前变动。
或按在湿地，用荐席裹（角埋瘗）〔着〕，其尸卒难变动。更详月头、月尾，按春秋节气定之。
盛热∶尸首经一日，即皮肉变动，作青黯色，有气息；经三、四日，皮肉渐坏、尸胀、
蛆出、口鼻汁流、头发渐落。
盛寒五日，如盛热一日时；半月，如盛热三、四日时。
春秋气候平和，两、三日可比夏一日；八、九日可比夏三、四日。
然人有肥瘦、老少。肥少者易坏，瘦老者难坏。
又南北气候不同，山内寒暄不常，更在临时通变审察。
In the three months of spring: After two or three days, the flesh color around the mouth, nose, abdomen, both hypochondria, and chest becomes slightly bluish-green; after ten days, foul-smelling fluid (pi feng qie, meaning swollen and odorous) flows from the nose and ears, accompanied by swelling. This occurs in obese individuals; for those who have been chronically ill and emaciated, these signs appear only after half a month.
In the three months of summer: After one or two days, changes in flesh color begin first on the face, abdomen, both hypochondria, and chest; after three days, fluid flows from the mouth and nose, maggots appear, the whole body swells, lips evert, skin decays and peels off, and eruptions arise; after four or five days, hair falls out.
When covering a corpse during the hot season, the floating skin at injured sites is mostly white, while undamaged areas remain blue-black, making definite traces of injury invisible. If one avoids the stench and relies solely on superficial inspection, errors often occur. In cases of slight doubt, the floating skin must be peeled away; if there is an injury, the blood underneath will be clearly visible.
Furthermore, in the hot season, although no maggots may yet be present in the nine orifices, maggots may appear first in the temporal region, within the hairline, on both hypochondria, or inside the abdomen, indicating injuries at these specific locations.
In the three months of autumn: After two or three days, changes in flesh color begin first on the face, abdomen, both hypochondria, and chest; after four or five days, fluid flows from the mouth and nose, maggots appear, the whole body swells, lips evert, and eruptions arise; after six or seven days, hair falls out.
In the three months of winter: After four or five days, the flesh color of the body turns yellowish and tight, with slight changes; after half a month, changes begin first on the face, mouth, nose, both hypochondria, and chest.
If placed on wet ground and wrapped in straw mats [or buried], the corpse changes very slowly. One must carefully consider the beginning and end of the lunar month and determine the state based on the solar terms of spring and autumn.
During intense heat: After one day, the skin and flesh change, turning blue-dark, with residual breath; after three or four days, skin and flesh gradually decay, the corpse swells, maggots appear, fluid flows from the mouth and nose, and hair gradually falls out.
Five days of intense cold are equivalent to one day of intense heat; half a month of intense cold is equivalent to three or four days of intense heat.
The climate in spring and autumn is mild; two or three days correspond to one day in summer; eight or nine days correspond to three or four days in summer.
However, individuals vary in fatness and thinness, youth and old age. The obese decompose easily, while the emaciated and elderly decompose slowly.
Additionally, climates differ between north and south, and mountainous areas experience irregular temperature fluctuations; thus, flexible observation and examination are required on-site.
