"More than 6,000 ducks in my duck farm need to be relocated to a safe place as they are trapped in a flood zone," a villager told a traffic police officer named Yi Yurong in the city of Jurong, Jiangsu province at 2 p.m. on July 5.

Yi left for the duck farm immediately after he received the call. At that time, the water level in Jurong's Nanhe Dyke was already quite high, and the duck farm with more than 6,000 ducks was near the dyke. 

Yi controlled traffic around the duck farm to ensure that a truck, by which means the ducks would be transported, could arrive at the scene quickly. 

Confronted with the danger of a dyke breach, Yi and another traffic police officer volunteered to help workers at the farm drive the ducks onto the truck. Their help was particularly valuable since the farm had too few workers to wrangle so many ducks at the same time. 

The two traffic police officers, together with the farm's employees, worked on their task from 7 p.m. on July 5 until 2 a.m. on July 6. 

Due to continuous torrential rains in Jiangsu in recent days, many places in the province have been affected by flooding. The city of Jurong is one many flood-affected areas in Jiangsu.
