Yinzhen was aware of this situation, which shows that Jing'e was indeed quite knowledgeable about the local conditions.

Yinzhen: "That's well said. I saw your proposed solution yesterday. Now, let's hear it. The Minister of Works is here today. He has also participated in river management before. Let him hear what he thinks."

Jing'e: "Yes"

"This servant has inspected the area and found that the reason there is so much silt in the river is because the river passes through a place where the soil is loose and there is more sand than soil. Therefore, the sand and soil in the strata are easily washed up by the water flow. The section of the river in front of us happens to be on a higher elevation, and the riverbed is mostly soil with almost no sand. That's why the silt washed down from the upper layers has accumulated here."

The servant's solution was to build two channels at the source of Nashado, with the original channel sandwiched between them. This would avoid the problem of siltation in the riverbed. Cement could be used to lay a layer of cement in the riverbed, which would prevent the silt from being washed away.

Because opening two more waterways will allow for water diversion, which will better reduce the impact of water flow on the river dam. If these two waterways are completed, the old waterways can be sealed off and the silt in the original waterways can be cleared away while the two newly built waterways are in use.

After the cleanup, cement will be laid on the original riverbed using a similar method before reuse. Having three riverbeds in operation simultaneously for three days will greatly reduce the risk of erosion of the riverbanks. With three riverbanks in place, even continuous heavy rains will better facilitate water flow, thus making it easier for residents along the river to access water.

The Minister of Works was newly promoted by Yinzhen. The original Minister of Works was assigned to another place. The current Minister of Works is named Bu Shunda.

The Ministry of Works is not unimportant, but in terms of its status in the imperial court, it is not ranked high among the Six Ministries. However, this department is highly specialized.

Throughout history, the Ministry of Works has not been given particularly high importance, but Emperor Yinzhen did attach great importance to this department, and therefore also valued Bu Shunda's opinions.
