Zhang Guoli visited the emperor incognito to punish the bully. What movie is it?

The TV series Kangxi travels incognito.

At night, in the blacksmith's room in the palace, Kangxi was learning to build an iron plow head with bare arms from the monk Fa Yin, and the ministers were waiting in the south study. After Kangxi returned to the south study, Mr. Tu Tu said that Hongyuan Road, the magistrate of Qingzhou, Shandong Province, played, and Luo Shichang, the magistrate of Wulian County, divided the tax grain in the warehouse and distributed 300,000 sorghum millet to the farmers who were preparing to go to Beijing by water.

And Mr. Tu Tu claimed that Luo Shichang argued that he wanted to buy benevolence and righteousness for the emperor. Kangxi was furious and ordered Luo Shichang to be severely punished. It turned out that Luo Shichang was arrested by the Ministry of Punishment for giving farmers tax grain as seeds on credit in order not to miss the farming season.

Kangxi heard from Fei Yi that there are still refugees and some people have starved to death. I can't believe it. In the early morning of the next day, Kangxi asked the ministers to dress up as refugees, and the ministers learned it vividly. Kangxi ordered Sandezi to write down the ministers who played refugees.
