Lin Zhou, a veteran product manager in the 21st-century internet industry, transmigrates to the 1990s after overworking himself. He becomes a technician at a state-owned electronics factory in a southern town that's on the verge of bankruptcy. Drawing on his ahead-of-his-time business acumen, he can accurately predict consumer trends, transform traditional goods with product-oriented thinking, design marketing strategies, and quickly learn to adapt to the times. At first, he is only out to “make a quick buck and get back to the modern era.” But gradually, he's moved by the warmth of human relationships in the 1990s and the passion of fellow entrepreneurs. In the end, he puts down roots in his era and becomes a “wave-setter” driving the upgrading of local industries, transforming from someone who lives for himself into someone who helps others.
