Seven modern project supervisors traveled through Bianjing in the Northern Song Dynasty, using the three-inspection system to reinforce the city walls, improve the formula of blue and white porcelain, and design ancient elevators. When modern supervision regulations collided with the craftsman spirit of the Song Dynasty, they guarded the bottom line of quality amidst business wars, floods, and imperial examination turmoil, only to find that they were the reincarnation of a thousand-year-old craftsman. When the time and space rift opened, they used their ingenuity as an anchor to build a quality monument that spans thousands of years at the intersection of ancient and modern times.
