I've found some sources that show China has a relatively low intentional homicide rate. For example:
Wikipedia's List of countries by intentional homicide rate cites the UN Office on Drugs and crime to say that China's intentional homicide rate is 0.5 per 100,000 inhabitants per annum, putting it 174th highest on a list of 195 countries.
The World Bank also puts it around 0.5 per 100,000 in recent years.
China's Global Times puts homicides at 0.56 in 2021.
Is the intentional homicide rate extremely low in China?
