From the reign of Emperor Xuanzong of the Tang Dynasty to the reign of Emperor Daizong of the Tang Dynasty, during the prosperous period of the Tang Dynasty, trade along the Silk Road was unprecedentedly prosperous. Su Jinyu, a young man from Chang'an, and his wife Li Mingyue, based on integrity and innovation, started from the market in Xishi. They made a name for themselves with novel products such as crystal candies and perfumes. They took the lead in establishing the Universal Business Alliance and built a trade empire across Europe and Asia. He went to Europe twice to open up trade routes, and experienced storms in the Indian Ocean, pirate attacks, and cultural competitions with the Frankish Church. He resolved the crisis with wisdom and spread Tang products and techniques to Constantinople, Rome and other places. Internally, he assisted Suzong of the Tang Dynasty. Emperor Daizong of the Tang Dynasty implemented the New Deal, smashed the collusion conspiracy between the old aristocracy and Tibetan and Arab forces, used the power of business alliances to stabilize the border and smooth water transportation, and even created the Chang'an World Expo, making Zhuque Street the core of trade and cultural integration among all nations. Su Niantang and Su Nianyue, twins of the Su family, have shown business talents since childhood. From trouble-making innovation to taking charge of their own business, they inherited the ideas of their fathers, empowered commerce with technological innovation, and resolved international disputes with trade mediation. Three generations spent their lives writing legends, from commercial wars in the streets to intrigues in the court, from stormy seas to foreign affairs, settling the world with trade and forging peace with ingenuity, making the Silk Road a link of peace between the East and the West, and leaving a colorful and eternal chapter in the picture of the prosperous Tang Dynasty.
