Recently, there have been a large number of reports on the Chinese Internet in the form of news, information, microblogs and long articles about China's development of private "security companies", "military companies" and "mercenary groups", which have aroused the attention of the majority of netizens, and many people have also participated in these discussions.
With the westward extension of the Belt and Road Initiative, there are a large number of infrastructure construction projects such as ports, docks, bridges, culverts, roads, railways, airports, oil and gas pipelines, as well as other industrial and mining enterprises. There is no doubt that China has a growing interest abroad.
Some of China's overseas engineering projects, such as the Dasu hydropower project in a canyon in northwestern Pakistan of the China-Pakistan Economic Corridor, have occurred, causing many deaths and injuries of Chinese engineers.
This is a typical case, which shows that some foreign terrorist forces have targeted China's overseas projects and extended their reach out to China's "One Belt, One Road" project. It is an extreme test of China's safe operation of overseas engineering projects and industrial and mining enterprises.
In recent years, terrorist attacks in North Africa, the Middle East and other places have shown a clear upward trend, and the influence of the Russia-Ukraine war and the Palestinian-Israeli conflict has gradually spilled over. Now, not only ships sailing on the Red Sea have been attacked by missiles and drones, but there have also been cases of drone attacks on merchant ships in the Indian Ocean.
Recently, foreign media, including Russia's **, noticed that the senior management of several important Chinese security companies, such as Anbang Security Group, CEFC Zhongan Group, and Dewei International Security Group, gathered in Beijing to discuss important matters.
Based on this, it is believed that China will develop private security companies and even "military companies" and set up "mercenary groups" to protect a large number of projects that China has invested overseas, including infrastructure construction.
Of course, this is just speculation by foreign media, and the essential characteristics of socialism with Chinese characteristics determine that China will not set up a fully armed security company like Russia's "Wagner" that is fully equipped with guns and combat vehicles and can be deployed in actual combat. In fact, "Wagner" is a private "military company" with the character of a mercenary.
At the same time, China will not establish a private military and security consultant like Blackwater International, which was born in the military-industrial complex of the United States, and cooperates with the United States to train mercenaries and security companies trained by the Marine Corps.
In fact, the majority of netizens do not have to worry about China's security work in overseas infrastructure projects and industrial and mining enterprises, and China has security measures and emergency response measures for possible serious security incidents.
In projects invested in Africa, the Chinese side generally has security personnel. He Jianguo, played by Wu Gang in the film, is the former commander of the reconnaissance company of the 14th Group Army of the Southwest Military Region of the Chinese People's Liberation Army.
After retiring from active service, the character in the film came to work as a security supervisor in a Chinese-owned factory in Africa, and he was equipped with firearms such as Type 56 submachine guns that could be used in battle at any time. 
In the past, state-owned enterprises had security departments (sections), joint defense team members, youth commandos, etc., all of which were used to protect factories and maintain social order.
With the wisdom of the Chinese, in overseas investment projects, security work is extremely important, and sufficient security forces will be deployed according to and combined with the local situation to ensure the safety of engineering projects and industrial and mining enterprises.
