Korean pine is a precious tree species distributed in the northeast of China, it is precious and ancient, distributed in Changbai Mountain and Xiaoxing'an Mountains.
Korean pine is also a precious economic tree, while wild Korean pine needs to grow for a full 50 years before it begins to set seeds.

Falling pine nuts are the seeds of pine trees in Yunnan and Guizhou, because the main production area is in Yunnan, so it is also known as Yunnan pine nuts.
There is also a kind of pine nut that is not a native pine tree in our country, but it is also quite popular in the Chinese market, this pine nut is a pine nut produced in Pakistan, Afghanistan and other places, known as Brazilian pine nut.
In the past, pine nuts were the food of squirrels and other animals that lived on pine nuts, but in the past, pine trees grew freely in the mountains and fields, and the pine nuts were layered and covered with branches.
Nowadays, with people's awareness of the nutritional value of pine nuts and the development of the pine nut processing industry, pine nuts have become the most familiar nut snacks we are most familiar with.
- Why was it unpopular?
So, why have pine nuts, which have been eaten since ancient times and are rich in nutritional value, have been neglected in rural areas?
Although pine nuts have been eaten for a long time, the fact that pine nuts can be eaten is only recognized by some people, and many rural people do not know that pine nuts can be eaten at all.
Therefore, the peasants at that time did not realize the value of pine nuts, which were buried in the pine tower, which was so hard that people could not see the scene inside, so they naturally did not pick up these pine nuts and let them scatter on the ground.
For farmers, pine nuts may be most useful as firewood, and besides, pine nuts are not common in all seasons, so people have less time to touch them, and it is more difficult to realize that there is fruit in them and they can be eaten.
——Expensive cost·]—
Now, people realize the value of pine nuts, and the love of foodies for pine nuts has doubled the value of pine nuts.
And it is not easy to pick pine nuts artificially, the pine trees are extremely high, the highest can be more than 20 meters, the pine nuts are hidden in the pine needles, people pick, not only to climb the tree, but also to prevent themselves from being pricked by the pine needles.
The danger of picking pine nuts and the timeliness of picking pine nuts make the labor cost of picking pine nuts extremely high.
Pine nuts usually grow in the deep mountains and forests, transportation is also more time-consuming and laborious, plus pine nuts also need to be processed again, expensive labor costs plus processing costs, so that the price of pine nuts is constantly rising, a pound can be sold for sixty yuan **.
Today's pine nuts can no longer wait to fall to the ground, and most of the natural treasures in the countryside have been excavated by people, and pine nuts are one of them.
