shapeshifting

In Huizhou(徽州), there was a top scholar named Dai Youqi(戴有祺). He and his friends, having drunk too much, strolled outside the city to admire the moon, reaching the Hui Long Bridge(回龍橋). A person in blue, carrying an umbrella, approached from the west side. Upon seeing Dai, he hesitated to cross the bridge, appearing fearful. Suspecting him to be a thief, Dai stepped forward to interrogate him. The person in blue claimed, ‘I am an officer from the yamen, sent to apprehend someone.’
