A total of 2,105 police officers have died and 22,977 have been injured while on duty since the 18th National Congress of the Communist Party of China (CPC) in late 2012, according to the Ministry of Public Security.
In 2016, 362 police officers died while on duty, the ministry said.
During the three-day holiday for Tomb-Sweeping Day, people across the nation commemorated police officers who have died.
The China Police Daily launched a section on its website for online memorial activities, with millions of visits and more than 6,400 comments.
Tomb-Sweeping Day, or Qingming, falls on Tuesday, when Chinese people honor their deceased loved ones by visiting tombs and making offerings.
