Corrupt officials visit fortune tellers.

The movie is called mental arithmetic!

Jin Dacai, a poor scholar, was frightened by mistaking the cow for a ghost in the dark, and the villagers who lost the cow looked around. His wife urged the poor scholar to tell the villagers in an unpredictable way that they had found the cow, and the villagers really found the lost cow, and they were convinced that Jin Dacai had magical power. Jin Dacai, revered as "God's Calculator", was surrounded by villagers and went to the provincial capital to beg for rain. The scholar accidentally ran into the rain and became more famous. He was connected to North Korea to find the emperor's lost property. Jin Dacai, who was in great fear, let the governor who stole the treasure lose his vigilance, and finally revealed the clues and found the treasure for the emperor. From the small village to the imperial court, the play exposes the deeds of clever people who are scheming everywhere step by step, and also reflects the social habit of listening to good words and muddling along. The frankness of the little people in the play contrasts with the confusion and strength of all kinds of characters, which provides the audience with another kind of reflection of superficial mentality that only looks at the surface and does not seek the inner.
