According to Zhou Yuzhong, a lawyer from the Yingke Law Firm who specializes in replica gun cases, the 1.8 joules per square centimeter threshold in the Chinese mainland is an 11th of the threshold used in Japan and Taiwan, and a quarter of the standard adopted by Hong Kong and Macao.
"By the 1.8 joules per square centimeter definition, the bullets can barely create a bruise on the human skin let alone shed any blood," Zhou said.
"Those who buy what were considered toy guns in Taiwan and Hong Kong will be charged with major felonies in the Chinese mainland. It looks almost like a farce," Zhou noted.
Zhou said his clients in gun cases come from all walks of life, including law enforcement staff such as police officers and judges.
One of his clients, Meng Qingwu, who served four years in a prison in Shenyang, Northeast China's Liaoning Province after selling seven replica guns in his toy shop in 2009, shared a cell with three prisoners on death row.
"It felt like a nightmare. One of my cellmates had killed four people and was still able to sleep soundly at night. I never quite understand how I deserved to be locked up in the same room with a bunch of murderers when all I did was play with toy guns," Meng said.
Lü Hongwu, a former judge from Jinhua, East China's Zhejiang Province who was sentenced to three years in prison with a three year reprieve for owning two BB guns, said the government has failed to notify the public of their 2010 change of policy.
"It came very suddenly when what used to be toy guns became defined as firearms. This includes rifles used in amusement parks to shoot balloons for prizes. If the Ministry of Public Security had broadcast it on TV or made public announcements in newspapers when they changed the criteria, people would oblige. But it did so quietly and many people became criminals without knowing it," he said.
Lack of legal support
Since the new definition was implemented, the number of gun cases has significantly increased.
According to data from the Ministry of Public Security, law enforcement officials busted over 9,000 cases involving making and selling guns from 2011 to 2015, arresting more than 80,000 people.
"In a lot of these cases, the so-called suspects had insisted that they had no idea that the 'toy guns' they purchased or sold are legally firearms. Therefore it is common for them to feel the verdicts are unjust," Chen Zhijun, a professor from the People's Public Security University of China, wrote in a paper published in the Journal of the National Prosecutors College.
He cited an example where up to 90 percent of the gun-related cases processed by Daxing district court in Beijing from 2010 to 2012 fell into the aforementioned category.
Chen admitted that the gun definition provided by the authorities falls far from public expectations and fails to keep a balance between maintaining social stability and safeguarding personal freedom.
"The replica gun cases usually have no victims. The suspects are either military enthusiasts or small businesspeople who have no intention to break the law," Zhou said.
Since 2011, Zhou has petitioned multiple times to the State Council and the National People's Congress (NPC) to abolish the current definition. Similar proposals were brought up at this year's two sessions by the Chinese People's Political Consultative Conference (CPPCC) member Zhu Zhengfu and NPC delegate Cai Xuefen, both of whom proposed that the standard be raised from 1.8 joule per square centimeter to 16.
"The current definition lacks legal support and is entirely based on an internal document of the Ministry of Public Security which has then based on industry standards. The core issue here is to prevent the administrative power of the police from meddling in legal affairs," Zhou told the Global Times.
He claimed that these cases often create judicial chaos and infringe upon citizens' rights and personal freedom.
"The ideological root of China's strict gun control policy is the long-existing gun-phobia in Chinese society. Inaccurate media reports that confuse replica guns with firearms and those that exaggerate the dangers of replica guns also contribute to the sentiment," Zhou said, adding that the government should differentiate different guns and recognize that the low-end ones are toys.
Zhou's opinion was echoed by Chen, who urged in his paper that China should carefully revise the current definition of firearms, especially for air rifles.
Ruan, on the other hand, defends the current criteria.
"Some of the rifles may not be able to deter the police force but can definitely scare off common citizens, which is not conducive to maintaining stability," Ruan said.
"It's not the definition or the criterion that created all the issues. The criterion will work better if the Criminal Law can be applied more flexibly," he noted.
