Ding Wei was a great official in the Northern Song Dynasty.

During the reign of Song Zhenzong, a fire broke out in the palace. Overnight, a large area of palaces, terraces, halls and pavilions became ruins. In order to restore these palaces, Song Zhenzong put Ding Wei, the Duke of Jin at that time, in charge of the restoration project. At that time, to complete this major construction project, there were three major problems: first, a large number of ruins and garbage needed to be removed; Second, it needs to transport a lot of wood and stones; Third, we need to transport a lot of new soil. Whether it is transporting garbage or transporting building materials and new soil, it involves a lot of transportation problems. If the arrangement is improper, the construction site will be chaotic, and the normal traffic and life order will be seriously affected.

Ding Wei Song Dynasty, after studying the project, formulated such a construction scheme: firstly, several large deep ditches were dug from the construction site, and the excavated soil was used as new soil for construction, thus solving the problem of new soil. The second step is to introduce Bianshui from outside the city into the dug ditch, so that the wood and stone can be transported by rafts and ships, thus solving the transportation problem of wood and stone. Finally, after the material transportation task is completed, the water in the ditch will be drained and the garbage from the construction site will be filled into the ditch, so that the ditch will be leveled again.
