(Imperial Examination + Time Travel + Micro Group Portrait + Golden Finger + Teaching)
A modern teacher who traveled through time has taken root in teaching in ancient towns with his timeless educational philosophy and an "agricultural product exchange system". He can't teach stereotypes, but he can teach patterns; he can't write strategies, but he can cultivate talents as prime ministers and assistants.
When his students left the town one by one and went to the temple, when the children from poor families began to shake the foundation of the family, the entire dynasty was asking the same question.
Who is that teacher in Qinghe Town?
