If you want to fight in actual combat, go to Guangdong, Guangxi, Yunnan, Xinjiang and Tibet Frontier Corps. The surrounding environment of these places is complex, there are many cases of smuggling and drug trafficking, and there are many opportunities for special police to actually fight.
Sacrificing for the country is the true nature of men, but people are raised by their parents. Life is precious. Even if you enter the border guards, don't take unnecessary risks!
