Xiao Yue rescues a red fox that has been shot with an arrow in the mountains and names it Xiao Hong. Unexpectedly, the fox is remarkably intelligent, able to detect the scent of medicinal herbs and identify valuable plants. It leads Shen Qingshan's family to dig up wild ginseng and harvest dendrobium, helping them go from struggling to put food on the table to opening the Shen Family Herbal Medicine Shop. But success attracts trouble. Sun Guangfu, Boss Qian, and Boss Zhou take turns making things difficult for them by obstructing permits, blocking mountain roads, and mixing counterfeit goods into their supplies. Starting with nothing but a handcart, Shen Qingshan establishes a cooperative and opens a processing factory, while the red fox guides the way and repays the family's kindness. Harvest the big ones while leaving the small ones to grow, and the road ahead will be long.
