An old farmer named Lin Shoutian composed and sang "Agricultural Song" to guide farming, but the government misinterpreted "Sowing during the Qingming Festival and transplanting rice during the Grain Rain" as an anti-Qing code, and was imprisoned. Under severe torture, he persisted in his belief that "farmers only know the farming season, but they don't know anything about political affairs." When the son struggled to rescue him and the magistrate was about to interrogate him, this simple ballad originating from the land had already set off a storm that no one could have predicted between the countryside and the temple.
