Forest trees are inextricably linked to the social life of the Northern Dynasty period. In those days, the importance of fuel could not be ignored, not only for cooking and heating, but even for refining elixirs. Firewood, also known as steaming, was one of the most commonly used fuels at the time, usually made from tiny trees. This period coincided with a low temperature period in Chinese history, and the cold climate led to a surge in demand for fuel, which also led to the rise of fuel trading. There are many people whose livelihoods depend on making fuel.
Charcoal is also a common fuel, and it is necessary to go through incomplete combustion to make charcoal to produce a porous solid fuel that is dark brown or black. However, charcoal production is not as plentiful as fuelwood. During the Northern Dynasties, the production of firewood and charcoal depended on the harvesting and processing of trees, including the branches, stems, stems, leaves and other parts of the trees. Therefore, it can be said that the forest played a crucial role in the fuel supply during the Northern Dynasty period.
In addition, the forest trees also have a profound impact on clothing production. The importance of mulberry leaves is self-evident in raising silkworms, making silk, and making clothing. Both the emperor and the common people recognized the key role of Uesang in the production of costumes. Mulberry planting is regarded as a legal obligation, and the government has also actively promoted the cultivation of mulberry trees to meet people's demand for clothing raw materials. However, this system eventually collapsed in the middle of the Sui Dynasty.
In the food life, forest products also play an important role. During the Northern Dynasties, food supplies were once tight due to social unrest and frequent wars. Forest products have become an important alternative food product for famine relief. Various forest fruits, such as elm pods, have become food substitutes that cannot be ignored. At the same time, fruits and nuts also greatly enrich people's diets. Forest products were not only used as a staple food, but also used to make a variety of preserves, preserved fruits and drinks, providing a delicious choice for the people of the time.
On the other hand, trees also play a key role in the construction and decoration of homes. Various woods, such as pine, cypress, poplar and elm, are widely used in construction, including rafters, beams, etc. Furniture is also made of forest wood as the main raw material, and beds, tables, screens, etc. are all wooden products. The furniture and architecture of this period reflect the importance of trees in the living environment.
As for transportation, boats, cars and bridges rely on trees as construction materials. Wood such as tamaki is used in vehicle manufacturing, while trees on both sides of the road provide directional signs for traffic and improve the convenience of transportation.
Finally, trees also play a role in the field of health care. Various forest products are used to make medicines, for the treatment of various diseases and health and beauty. The branches, stems, skins, leaves, flowers, fruits and other parts of the forest are used to make medicines, providing an important resource for medical care.
To sum up, the social life of the Northern Dynasty period was closely related to the forest. Trees are not only a basic source of material, but also play an indispensable role in clothing, food, construction, transportation, and medical care.
