Give free rein to Party nature

党性大发 (dǎngxìng dàfā): give free rein to one’s “Party” nature

A play on the idiom 兽性大发 (shòuxìng dàfā), “to give free rein to one’s animal nature.” As a government official, one’s “Party” nature shines through in forced demolition, child molestation, and other public cruelties.
