Since Zixuan had led people to inspect the sites in person before, the first batch of work commenced in areas where the river channels were treacherous and prone to problems. A majority of the staff from the county office were dispatched to oversee the progress at various locations.
When it came to the deployment of manpower, the principle of proximity was of course applied. Villages close to the river sections were directly responsible for their construction, which made things much easier. Additionally, a portion of the sergeants stationed at the border was reassigned to the site by Zixuan. These guards were led by a deputy general, who was formerly a guard for the emperor. Li Mingrui had specifically sent him to facilitate Zixuan's work. This area was extremely important and too far from the capital, so it would be too cumbersome to request instructions for every emergency. Thus, the emperor gave Zixuan the authority to make decisions on the spot.
