It may not be as malodorous as the Body Farm at the University of Tennessee, but this "bank" in eastern China has at least as many different smells.

Police in the city of Nanjing are using the country's first human body odor bank to help train their dogs to find criminals.

The official Xinhua news agency reports the facility has 500 different smells that can be compared with samples found at crime scenes.

Reuters reports the smells are kept at a chilling 0 degrees Fahrenheit.

The bank's founder Song Zhenhua is quoted by Xinhua as saying, "This way the scent sample can maintain its freshness for at least three years."

At least three trained canines must provide identical reactions in order for a smell to gain a spot in the bank.
