Ning Shuangshuang laughed and said, "Picking dry firewood should be simple and not require picking it up from the ground. As the saying goes, 'a big tree has dead branches.' In this mountain forest, no one prunes the leaves, so there are plenty of dead branches. Moreover, these dead branches on the trees are not on the ground, so they don't absorb moisture. They're very dry, easy to ignite, and produce less smoke. We just need to find some dead branches up in the big trees and pull them down."
Over there, Yu Yingjie was also pulling dead branches from trees with Qi Qing, who was a bit doubtful and said, "I heard that dead branches on trees can sometimes come back to life after a year. Isn't pulling them down harming the trees?"
