On April 5, Xu Qichang, wearing a special made hat, burns mugwort leaves to drive wild bees into different beehives. Spring is the period of reproductive peak for wild bees. Xu has to find out anything unusual in the bucket of bees. If anything goes wrong, his wild bees will flee and find other honeycombs in the wild. [Photo by Lv Bin/asianewsphoto]
