Police in Dalian in northeast China's Liaoning Province have uncovered a gang selling guns online.
Police have detained 27 suspects for allegedly manufacturing, selling and possessing guns without licenses.
In addition, 105 guns, more than 1,200 bullets and 147 gun components were seized.
In August and September 2016, online trades in cartridge cases and gunpowder in the city caught the attention of police.
Investigation showed that a gang was manufacturing guns, selling them through WeChat, a popular chatting app and social network service, and delivering them by courier service.
The suspects were caught in January in 13 cities across the country.
Manufacture and sale of guns is banned in China, and members of the general public are not allowed to own guns.
Anyone found guilty of owning a gun can face up to seven years in prison.
