First of all, it's a long way. At present, many Korean pines with good yield in Northeast China are basically in deep mountains and old forests, and the outside ones are basically planted artificially, with more output than the wild ones, but the taste is not as delicious as the wild ones. Reaching the deep forest basically depends on two legs, so the whole process is very hard.

Then there is the hardship of the picking process. Because the fruits of Korean pine basically grow on the crown of the tree, even if you take a long pole, you can't reach it. Therefore, there are special workers to climb trees and lay pine nuts, but the workers have few climbing equipment and almost no safety protection. They can only climb trees by the strength of their limbs and climbing equipment. If you are not careful, you will fall from the tree. According to relevant statistics, when picking pine nuts in Northeast China every year, someone will fall from the tree.

Then the transportation of pinecones after picking is a problem, and the nearby Korean pine may be easier. If you go deep into the forest to find pine nuts, transportation becomes a big problem. Because of the impassability of vehicles, the process of transporting pine cones is basically manual. After manual loading, it can only be carried on the shoulders one by one, and finally carried to the place where the vehicle is located.

Finally, the drying process of pine nuts, artificial need to completely dry pine cones, knock off the hard shell, pick up the pine nuts inside. The whole process can only be done manually, and machinery can't be done at all, so the process from picking pine cones to picking pine nuts is done manually, so it takes a lot of manpower and time, and we can appreciate the hardships of picking pine nuts from the whole process.
