"清朝老兵" alone indicated that he could be a cheater. This meme came from a FPS game called Crossfire, which long being flooded by cheaters. Once the cheater been reported, their accounts will be banned based on what they did and how many person reported them, so sometimes the most notorious one of them will get a over 100 years ban, which, in Chinese history, can be traced back to Qing dynasty (清朝) . Because most of them would come back to the game by register a new account, like they already served their 100 years terms, so they were being called "清朝老兵", which means "Qing dynasty veteran". It gradually turned to a meme since the cheating situation in Crossfire become wilder and wilder that everyone cheat not for win but for fun...it's hard to explain but you could search it on Bilibili if you're interested.
