A national flag of China and a police flag are flown over Huangpu River on Monday to mark the Chinese People's Police Day.

Flying their flag and retaking their oath when entering the police force, Shanghai police celebrated the second Chinese People's Police Day on Monday.

The police reviewed their work in the past year and said they have been both smarter and more efficient in keeping Shanghai residents safe.

"Our goal is to make Shanghai a world-class safe city with highly effective police work," said Shanghai Public Security Bureau on Monday.

The number of criminal cases reported in all parts of the city last year was down 19.9 percent from the previous year, police said.

For the seventh year in row, all murder cases reported last year were solved, and for the fourth year in row, all robbery cases were solved before the end of the year, according to the police.

Over 96 percent of the burglary cases reported last year have been solved, police said.

Last year, police solved 13.4 percent more Internet and telecom fraud cases, and the number of suspects caught in those cases more than doubled that in the previous year, with about 960 million yuan (US$150 million) of loss prevented or recovered for the residents, police said.

The number of deaths in traffic accidents last year was down 13.7 percent from the previous year, and the number of traffic accidents caused by right turning trucks was down 57.9 percent after all trucks were required to pause when making right turns, police said.

The number of fire cases caused by e-bikes, which often result from overcharging of the batteries or using wires to charge the bikes from home, was down 9.2 percent last year, as more and more e-bike parking and charging spots were constructed at residential complexes and surveillance cameras which can automatically detect e-bikes in elevators started to be installed, police said.

E-bikes are banned from residential buildings around the city.

Third-party surveys show that Shanghai residents have felt safer and safer and got more and more satisfied with the work of the local police in the past nine years, Shanghai police said.

The Chinese People's Police Day falls on January 10 because 110 is the national police call. Traditionally, police hold various open-door and community activities for the residents on this day.

Reviewing the oath, presenting police skills as well as showing the theme MV were the ways that police officers working in prisons, juvenile reformatory as well as drug rehabilitation centers celebrated their day on Monday, according to Shanghai Justice Bureau.

As highlights, during the event, police officers from prisons and drug rehabilitation center gave the baton, shield, guns and explosion-proof performance, showing how they use their skills in daily training to imitate searching and arresting criminals.

In addition, a dance performance provided by the juvenile reformatory showed how officers tried their best to re-educate children who have committed crimes through traditional arts, such as traditional instrument, calligraphy and art tea.
