In recent years, there are emerging ways of picking in the growing area, by using hydrogen balloon.

In order to improve unsafe and inefficient traditional way, some farmers have begun to study and try new type of harvesting. But due to lack of experience, sometimes accident happens, such as couldn’t tie the rope to the tree in time to fix balloon led to the balloon was blown away by a gust of wind.

There is a saying in the growing region, “5kg of pinecones generate 0.5kg of pine nuts, 5kg of sweat generate a pinecone.”

Pine nut harvest is hard work, every kernel is hard-won.
