Time Trader: Shuttling Between Two Worlds in the 80s

Ma Chao only wanted to retrieve the jade pendant left to him by his grandmother from his biological mother, to sell it and pay for his father's leg treatment. Unexpectedly, he gained the ability to travel back and forth between the 1980s and 2025. In 2025, wars rage everywhere, but China stands firm. It is prosperous, democratic, civilized, harmonious, and free—the world's factory, the second-largest economy, an industrial powerhouse. In the 1980s, China's industry was backward, but its food, vegetables, and fruits were pure and pollution-free, without any tech or additives. Ma Chao discovers he can shuttle between the two eras. He brings modern clothing, watches, color TVs, and refrigerators back to that era of industrial scarcity, and brings pure green fruits, vegetables, and food from the 80s to the modern day. Ma Chao makes a fortune in both timelines. He vows to make the man who sheltered him happy and ensure his whole family lives well. Most importantly, he wants to help 1980s China take a shortcut, advance into the industrial age ahead of time, and reach the pinnacle of the world, showing those foreigners who look down on China what it means to return to historical status and be a true civilized power.
