Lin Shoushan, a legendary king of mountain produce, spends his entire fortune arranging a wedding banquet for his son, only to be despised by his son and humiliated by his in-laws. Finally awakened, he joins forces with his adopted son and daughter to return to his old mountain-foraging trade and embark on a path to success. Along the way, he puts his snobbish in-laws in their place, meets influential figures and charming women, gathers and sells mountain treasures, searches for national treasures, establishes factories to help farmers, and takes his business public with patented innovations, climbing step by step to the pinnacle of life. Three years east of the river, three years west of the river—never look down on a middle-aged man just because he is poor!
