The hereditary Marquis Heliancheng concealed his aristocratic status and hid in the old capital of the Republic of China as an ordinary landscaping worker. He relied on his superb planting skills to pretend to be a pig and eat the tiger. He used the pretext of trimming green plants on the street and taking care of the gardens of his private residence to quietly pass on intelligence and remove hidden enemy stumps. During the greening work that no one else suspected, he gradually stirred up the espionage chess game behind enemy lines and protected the secret defense line of his family and country.
