After starting his independent life at twenty-two, Hou Erqiang unexpectedly discovers that an old iron box left behind by his mother contains Republic-era land deeds. Possessing the skill to identify the value of old items, he puts down roots in the scrap business, walking the streets and alleys to make an honest living. He keeps clear accounts in his work and is fair and sincere with people, gradually improving his life with his sharp eye and upright original heart. During this time, he reaches out to help people in difficulties, secures projects, and gets to know the kind Miao Xiaoman. Others envy him for his hard-to-come-by opportunities, but Hou Erqiang deeply knows that while a keen vision is indeed precious, holding fast to one's original heart is the most precious thing of all. Opportunities are hidden among old items, but the most precious things in the world have never been gold and silver wealth.
